Is SkillSpeed too weak?

[Shurrikhan]

Thats not entirely true if considering trade offs of even the worst stat det as the baseline rather than just no substat.

I just specified "inherent", as opposed to the difference in "efficiency... of secondary stats". Getting somewhere too early, such that one has to wait until the normal time to use the skill, still doesn't cost you anything in itself; it just doesn't get you anything either.

Her explicit claim was that SkS is literally a damage-decreasing stat, not that it was merely an inferior choice. Her implicit claim thereafter was that a mere two pieces of gear being swapped away from could increase her damage by 20 percentiles merely by virtue of replacing SkS. Both are ridiculous. The stat's pretty bad on NIN. It is not, however, outright negative.

Heck... very early SkS is still technically better than early Crit, given that, say, a mere 534 SkS will improve roughly 77% (as per best NIN aDPS parse in Voidwalker S) of your damage by 2.46% for roughly 282 stat per 1% expected damage increase, or at worst about 290 when considering the GCDs spent triple-weaving, while Crit's nearest interval at 495 has an expected damage increase of only 1.44% (albeit across all damage), or a stat efficiency of 343 per 1% damage increase. It remains better until around 4k DHit+Crit or 3k+ Crit, outside of certain awkward intervals (where it takes an abnormally large stat jump to get from one effect tier to another). And that's on... the absolute worst job for SkS.

I apologize for seeming slightly sensational and misleading people, but if you do check my logs, it's actually more like a 15% increase than 20%, though it did jump from 40-something to 60%.

Though it should be kept in mind that:
1) The pieces of gear swapped out were the absolute worst offenders, 875 phantasm tome pieces with 400+ sks and det, compared to crit and dh. That's almost 1000 sks plus 500+ crit and dh. Minor adjustments to other gear also happened.
2) 1% dps increase is 10% parse rating. Parse is highly competitive and the difference between top and low parses is only around 1000 dps.

SS isn't too weak, it just doesn't benefit every job equally and has a diminushing return on the exact reason why it doesn't benefit every job equally.
And that reason is ogcd.
the more a job is dependant on their ogcd for performance (wether it is heal or dps), the less it will benefit from SS. SS doesn't affect ogcd (spare a few exceptions), so when your job has 30% of their dps based on ogcd, that's an issue. And as people mentionned, you have the issue of double weaving coming up at some point where you can't doubleweave without clipping.
You may also have rotation going off board depending on your SS where your gcd don't aligne properly (that was an issue for MCH back in SB)

This is why SS benefits heavily job which have their entire kit based on gcd (or most of it) such as BLM and SAM (and GUN if I understand right), or have burst window where SS help put an extra gcd WAR, DRK

So in short, if SS (and spell speed) would reduce ogcd CD or increase their damage, then it would become a much better stat for most job.
The effect would however have to be adapted to everyjob.
But that would be on a personal level, if SS would reduce ogcd CD, then some job would miss aligne their buff with other jobs and that wouldn't be good.
For instance, if a NIN with very high SS would end up with a TA on a 52s CD, maybe no other job in the party would be able to squeeze their burst window within that TA, making the benefit of that SS a bit counterproductive. (Same for DRG's jump or SMN Trance etc)

The most simple solution would be to just make ogcd damage scale from SS.
