An In Depth look at Dark Knight - Lvl 70 Raiding Guide

[Emiin]

Mapping out the fight is important, but sometimes fights end a GCD ahead of where you expect (suppose Sam crits multiple 50K hits), and TBN just further complicates this type of optimization since if you would have ended in the optimal place but the fight ended a GCD before (because of RNG) then the planned optimal uses of TBN becomes not optimal.

Typically, outside of O1S and O2S, TBN usage for DPS gains for self will be mapped out based on phase pushes/disconnects, as opposed to the entire fight itself, as those happen on the regular and at specific intervals. The main gain is always healer gcds/spot "healing" in order to better the raid, as opposed to self.

Considering if it replaces Souleater it's already a loss, I didn't take further math into consideration. But I'll make a nod to it. ^^

[Quor]

Throughout a fight, you’ll only know which GCDs you have replaced depending on which GCD you end a fight/phase with. Note, that this math does not equate to Bloodspillers gained naturally, as the (-140) modifier will not be present, and naturals are always a gain when used.
Overall, TBN guaranteed Bloodspillers averages out to a 10 potency gain when used regularly throughout your rotation. At some points it will be a loss, some it will be a gain.

I also talked about its utility in other sections. But again, you didn't read it, apparently.

I had a pretty long multi-page argument/discussion with several DRK's about the use of TBN, and many of them kept telling me that TBN, used in place of DA for dmg, was always a DPS loss. I mathed it out over a few different given periods of time and came to the same conclusion as you. Namely, there are discrete moments in time where using TBN for the 50 blood for BS is a dps gain over using DA. Likewise, there are discrete moments in time where using DA over TBN results in an increase in damage.

There's still a pretty large group of DRK's who see TBN as only a loss compared to DA, so the kneejerk is still strong.

[Graiggy]

In a day and age where an overwhelming amount of tanks are concerned with parses considering how easy these fights are, a lot care whether it is a personal DPS loss or gain, even if "negligible."

So far from what i have been reading about DRK on other forums. you are the only person that says to not use TBN. I am not level enough to argue with you but just pointing out that so far your the only one ive seen. Now as for living dead. I kinda agree you shouldnt get to a situation where that is needed. but it does make a good panic button.

[Chrono_Rising]

Also, just a minor clarification point, the soul eater potency is now 300, but the priority section for DA on soul eater vs siphon strike still reflects the 4.0 value of 280 instead of the 4.05 value of 300. This of course does not change the point at all, which is it doesn't matter which you DA its the same thing, but could be confusing for those mathing it out at home.

Just fixed that one actually, thanks for the heads up ^^

Agreed, it benefits healers greatly when used on yourself, and healers being able to cast an extra nuke should outweigh personal gains as it isn't negligible.

My argument for why it is less than stellar is that as our cap stone ability I feel that it is an unnecessarily large personal dps gamble for the small pay off it provides (140 potency gambled for a .625 expected gain), it is encouraged to be used frequently to make up for the defensive skills we lost or didn't have (procing 3.x reprisal for mitigation and free damage, or filling in a shield as form of hp restore to buy time), and the existance of a tank which has more utilities at no personal dps cost lowers the value of tbn overall. What are your thoughts on TBN overall?

[Emiin]

Instead of overall DPS utility I like to think of it as basically a better Shelltron. While Shelltron, with how blocking works, gets weaker as a defensive button with more mitigation, ours gets stronger; as both are taken into consideration after mitigation has been applied.

An attack brought down to 20k after mitigation - Shelltron only blocks 5k~of it, while our shield blocks 10k. Shelltron is really only better than TBN if you're taking a 40k+ hit, and that's typically never going to happen if you utilize the rest of your mitigation correctly.

I usually don't think of it as a DPS button and more of a healer utility one, unless I'm prepping for a Trick Attack window and I won't need it soon otherwise. Really helps when for mechanics/DPS reasons the healers aren't able to pay attention to you!

At this point you're just being nit-picky, in a general field of information that doesn't require it.

No, I'm really not. What this "general field" doesn't need is someone making Living Dead out to be a 20s invuln skill.

The literal only benefit LD has over Hallowed Ground is the shorter CD and a couple extra seconds of invuln on Holmgang. However, there's so many advantages that Holmgang and Hallowed Ground have over Living Dead that I won't even get into unless you really press me. You shouldn't even be approaching this subject in the manner which you are.

I listed an -average- potency gain of 10. As stated in the math this will not always be the case. If you read the math, you'd understand that. Every 3 TBN uses it will even out to 10 potency gained, and the cycle resets. Since you didn't read the math, I'll clarify it really quick - (110-40-60) = 10.

If you're gonna school someone, you might wanna make sure you know what you're talking about. What you got there is not an "-average-", it's a sum, so if you divide that by 3, then you'll have your average: 3.33

I get that you're feeling under attack and are defensive since you probably put a lot of time into this, but you're not the only one to speak falsely on DRK and you need to hear what I'm saying. You can't just completely ignore the fact that Souleater accumulates Bloodgauge, which is exactly what you did.

You broke it down like this:

Case (1): Bloodspiller replaces Hard Slash
Lost: 150p + 2400MP
Gain: 400p
Total: 400p - 150p - (140p) = 110p

Case (2): Bloodspiller replaces Syphon Strike
Lost: 250p + 2400MP + 1200MP
Gained: 400p
Total: 400p - 250p - (140p) - (70p) = -60p

Case (3): Bloodspiller replaces Souleater
Lost: 300p + 2400MP + 10 Bloodgauge
Gained: 400p
Total: 400p - 300p - (140p) - 10 Bloodgauge = -40p - (b) // where b is the potency value of 10 Bloodgauge

Grand Total: 110p - 60p - 40p - (b) = 10p - b

Are you seriously going to stand by the claim that 10 Bloodgauge is worth less than 10 potency? Your "general" guide gets awfully specific in questionable ways.

By all means, stress the importance of using TBN to get an extra Bloodspiller in a raid buff window, but if you're going to avoid in-depth math analysis, stay vague and just say that the loss/gain is negligible compared to the raid utility.

When you say stuff like TBN is a DPS gain on average and Living Dead is 10-20s of invuln, it paints a picture that doesn't exist and gives fuel to those who think "DRK is fine" but don't understand what's going on.

[Emiin]

Gonna drop the LD subject since we're not going to agree on it no matter the case. All invulnerabilities have their uses, it's up to the player and their raid team to decide how to use them. We do seem to agree that it does lead to more healer-ignorance for longer time. The exact time seems to be the only debate, which all depends on when and how you use it. All three invulnerabilities need to be healed afterwards/before/during. How your healers adjust to their use is up to you and your group. one LD I use effectively allows my healers to ignore me for 15-18 seconds, depending on when I use it and how I've prepped for it.


I'll agree that average was the wrong word to use, so I'll use sum instead; already changed. Average just sounds nicer in the grand scope of things, and is a more commonly used word.



As far as the blood gauge gained from Souleaters in regards to the TBN math, there's a specific reason I ignored it - because it becomes more convoluted than you'd imagine. The guide was meant for a further understanding of Dark Knight, not a full-nerd by the numbers understanding. I've gone full nerd on the math for TBN and decided it wasn't worth it to share. But since you're so inclined, I'll share the thought process behind it anyways.

In order to nullify the added gauge from the Souleaters replaced, you'd have to have 15 TBN casts. Hitting TBN on cooldown would land you in the 3:15 timeframe, including the one used on pull, at 0. Not only that, you have to consider the GCD that the bloodspiller granted naturally from not hitting the souleaters that you've replaced through TBN. I just tested a 3:20 striking dummy run and ended on Syphon Strike sitting at 32 blood. I could have used 9 TBNs within that timeframe and had it been a gain, and have no wasted blood. That, as well is where the issue lies with including the blood gauge within TBN math - how much blood will you end with at the end of a fight / phase? How many TBNs need to be added/removed? It's too much to think about. Don't.

A lot of things can happen within this 3:15 timeframe. One full opener, three trick windows, three brotherhoods, two embolden windows, 2 strategems, two hypercharged turrets, two-three foe requiem windows, two battlevoices, 2-3 aoe card draws, two litanies, and one potion.

Extending the math to include this would be nearly impossible, and for the most part, not worth the extra thought for the typical player, who this guide is aimed at. From what I can understand from your posted FFlogs entries, someone such as yourself. There is an extended amount of math that was involved in the bulk majority of creating this guide that I did not post throughout, as it is not necessary for the understanding required within the scope.

The TBN section of my guide even states that the thought process behind TBN usage is probably best not to even think about, and use it as you deem necessary. The current top players throughout many of the clockwork fights that would have minimal TBN usage do not even reach the 15-total TBN count. At the most, 12. At the least, 2. And many of these top players assisted and guided me on the math involved within my guide post, and agree that thinking further on it is not necessary for the bulk of players. It's for optimization. Some even ditched TBN unless it was completely necessary in keeping them alive through a mechanic.

The point of the TBN math listed was to state that the gain/loss with TBN was fairly neutral, and was not always a gain depending on what was going on with the fight, as opposed to what a newer player would believe based on the tooltip and asssumption that it makes a Bloodspiller "free."

[Lyth]

The math is fairly straightforward. Here's how it works outside of Grit.

Replacing Hard Slash:
50 blood = 1.2(400 potency) – 1.2(150 potency)
50 blood = 300 potency

Replacing Siphon Strike:
50 blood = 1.2(400 potency) – 1.2(250 potency) - 0.5 DA
50 blood = 180 potency – 1.2(0.5)(140)
50 blood = 96 potency

Replacing Souleater:
50 blood = 1.2(400 potency) – 1.2(300 potency) – 10 blood
60 blood = 120 potency
50 blood = 100 potency

Every three Bloodspiller actions, we have:
150 blood = 300 potency + 96 potency + 100 potency
150 blood = 496 potency
50 blood = 165 potency

Given that 1 DA = 1.2(140) = 168 potency outside of Grit, every full combo that you replace with TBN-Bloodspillers, you end up with a net 3 potency loss outside of buff windows. That's why you're seeing much lower usage on optimised runs, instead of using it on every cleave or tankbuster as some sort of DA replacement.

I can appreciate that most people don't want to know what is happening under the hood, but I don't think that you can simply ignore resources in your calculations on a primarily resource-based job. While I wouldn't have personally expressed it so harshly, I think it's feedback worth taking on board.

While I think it's important to be able to justify whether TBN is a gain or loss and whether it's a marginal one or a significant one, I personally think that the Bloodspiller math becomes much, much more important when you start looking at Delirium and the timing of fight mechanics that influence your uptime. Most buffs give you partial marks based on your uptime in the window. Delirium does not.
