DRK Rework

[kashi11]

First, forgive me that I will not use the per-argument format the way you do, hope you don't mind. (°u° )

Don't worry about it, I definitely don't mind. ^_^

Dark Mind - While you have a fair point regarding uptime and DRK not having an anti-knockback ability unlike almost everyone else in the game, I personally think that the trend of 30s / 60s "cheese knockback mechanic" abilities is a bad thing for the future of fight designs. Knockback mechanics can now be entirely circumvented on demand, rather than having to actually do the mechanic properly. In my personal opinion I'd nerf said cooldowns to 90s+ to make the cooldown placement matter more. Back in the statement of knockback immunities I suggested reworking some role action skills to rotate out of the list and be swapped with other skills that are more situational but still good, giving you more of a choice. Simply put, Tempered Will in role actions.

While I agree with you, shuffling role skills is a bit 'out of the scope' of what I think would actually be done by the devs anytime soon. That being said, cheesing knockback mechanics can currently be done by every Job, save DRK, BRD, and MCH.
Dark Mind, similar to holmgang, is used as mitigation. Players would need to determine whether they could use Dark Mind as a knockback protection and still have it be up in time to be used as a mitigation cooldown.

Carve and Spit - Without taking Crit and DH buffs into consideration, the equalizing of chances is overall not too bad. However the benefit is not so great if you play in a party setup that boasts with crit and direct hit buffs (DRG, SCH, BRD, etc). Theoretically speaking, we have a 15% chance of Crit without buffs and about 40% with buffs (Battle Litany + Chain Strategem). If it was a single hit, it would be a 40% chance to crit and either is or isn't and be done with it. With a three-fold attack that calculates criticals individually, you have to go through each hit with a 40% chance. To get the same benefit as single hit CaS, all three need to crit, which in theory is a chance of 40%*0.4*0.4, which results in a chance as low as 6.4% to get the same output of hitting a single critical hit. Depending on the crit damage multiplier you have at that moment it could have devastating effects on criticals.

In a vacuum of 1 instance yes, however, battle litany is on a 2 min cooldown, so lets say you get 6 CnS in a 12 min fight under those buffs all happening at once for a rate of 40%. (2.4) 2-3 CnS will be Crit/DH. As a 3-fold attack thats 18 hits and (7.2) or 7-8 Crits/DH, or 2.33-2.66 original CnS. On average over the course of a fight, partial CnS Crits/DH can smooth out when the current CnS doesn't Crit/DH

About the explanation of your Blood Gauge gain - while indeed it would end up the same MP cost of TBN, it lacks the possible penalty for such a high gauge gain compared to TBN. If using DA-CaS would have some sort of risk of not delivering blood given specific circumstances (like TBN with shield not breaking = loss) it would justify the 50 gauge on top of being one of the heaviest hitters, otherwise it would end up as a riskless Delirium setup (which gives back the 2400 mana already). So either a condition where gauge gain can fail or it should be lower, but 30-40 instead to not have as big as a gap as I suggested earlier.

TBN can still be a loss, even if it breaks. In fact, most threads and math point to it being a loss more often then its a gain, however we are only talking in the neighborhood of +/- ~10 potency. In order to understand the math behind mana to blood DPS weights we have to acknowledge the GCD shift from using bloodspiller vs oGCD DA.

standard combo with 1 DA use:
{150+250(+70)+440}/3 GCDS = 303 Potency/GCD

standard combo with Proc'd 50 Blood (from either TBN or CnS):
{150+250(+70)+300+400}/4 GCDS = 292.5 Potency/GCD

now looking at the same 3 GCD window, we can see how the Potency/GCD is affected by GCD shift due to Bloodspiller.

Replacing Hard Slash:
{400+250(+70)+300}/3 GCDS = 340 Potency/GCD

Replacing Syphon Strike:
{300+400+150}/3 GCDS = 283.33 Potency/GCD

Replacing Soul Eater:
{150+400+250(+70)}/3 GCDS = 290 Potency/GCD

Now the next part I'm only going to talk about CnS, because it's are topic of discussion and this is where it diverts from TBN (because of differences in recast time)

CnS is on a 60s recast or 24 GCDs or 8 sets of 3 GCDS.

7 sets will all be the standard combo at 303 Potency per GCD

One set will be one of the above, depending on which GCD gets replaced by the Bloodspiller proc'd by CnS.

Replacing Hard Slash is a gain with:
(7*303 + 340)/8 = 307.62 Potency/GCD +4.62 Potency/GCD

Replacing Syphon Strike is a loss with:
(7*303 + 283.33)/8 = 300.54 Potency/GCD -2.45 Potency/GCD

Replacing Soul Eater is a loss with:
(7*303 + 290)/8 = 301.37 Potency/GCD -1.63 Potency/GCD
