how much spellspeed do i want for blm?

[Mhaeric]

I really, really wish there was a viable way to have different sets for casters at endgame. As a RDM main, I definitely do not want spell speed which forces me to use crit/dhit gear on my BLM when I play it. Not that it's bad like that, but I would definitely prefer a full SpS build for him without having to sacrifice ilevels.

The sheet's not a sim, but it tries to give a fair model to how stats impact dps given the pps model of blm. Furst would be better to go over the nuances behind it as it's not one I've worked on directly beyond all my early sub stat work for the game in general. Something like Yunalesca's BLM AI which came up with the megumin rotation is more along the lines of something that can better account for rotational variances. However, for the intents and purposes of seeing what gear options are stronger, especially without changing the GCD value, the sheet more than serves its purpose as a gear comparison tool.

Yes, DH can be better and more impactful earlier on, although being a linear function it does suffer from relative diminishing returns just as Det does. This is DH vs Crit that will always be correct, the full range and when it's within more realistic bounds. Translate those to points with a 3300 level mod and Lv. 80 values. Can solve with the surface diagram or just solve by plugging the numbers in and working it out that way.

The problem is when people use the data and calcs incorrectly to come up with those conclusions. The goal isn't about getting the best mileage out of your points, yes that matters, but what ultimately matters is what combination is achieving the greatest total damage possible. Speed muddies the water, but if all that's being looked at is Crit, DH and Det for DPS jobs? That's really easy to resolve.

The sheet doesn't account for rotational gimmicks at certain speed values, and the min crit set still outperforms the crit set on average. That being said, while having a slightly lower average, people still like the crit set because the variance is higher. So if you go for a lot of runs in a fight you can fish for "the god run" more easily with the crit set.

The rotational gimmicks you can pull off with high enough sps are usually not that easy to do in actual fights without putting yourself at risk to drop eno.

In any case "crit outscales dh at X" is just an inherently flawed thought. You don't look to outperform a single stat, you try to maximize your total expected damage. That means you try to find the maximum of a 4d manifold which is bound by the total amount of substats. The problem is that gear choices dictate a major part of the substats and as such we aren't just looking at a circle around 0 with radius Σ(substats). Finding this maximum is non-trivial and we bruteforce a solution for gearsets by going through a huge part of the about 20^9*10^3 permutations in gear and melds. You could also just settle for an analytical solution since the problem is just an optmization problem (https://en.wikipedia.org/wiki/Lagrange_multiplier) but once again gear based substats and tiering makes this non trivial.

In any case, instead of blindly following magic numbers you are way better off just using the tools the community already created.

It is easy to resolve ignoring speed. However blm being the only job (except maybe sam?) that can use speed well, it kind of forces it to be a factor. The gear this tier made it almost too easy to stack sps up and it scales so well, but most of that gear seemed to favor pairing it with dh than crit.
