Warrior changes are unwelcome.

[Fyce]

Except that most of warriors damage is because of berserked FC's during trick attack windows, which every other job also uses buffs during, which your berserk windows no longer line up with correctly.

Are the math actually done on that one, or are you just assuming that missing 1 out or 3 Trick Attack window is detrimental because it seems like it?
Berserk doesn't exist anymore at level 70 btw.

And what about all the DH materia you're melding in your gear that is now also useless during berserk Inner Release.

That doesn't matter as we'll be changing gear soon (and that we can unmeld some of it and get a few back anyway). And if Direct Hit isn't BiS anymore, then so be it. It's not like Materia VI are hard to get. Also, we already knew that Crit would outdo DH anyway... but now, for WAR, Crit is probably the primary substat to focus on without even having to check at the upcoming stat weight.
Anyway, this change just gives more weight to Crit, and less to DH. Which should raise SS, Det and Ten.

If you think it's only a small decrease, you're not looking at the whole picture. The old 30% buff was way more powerful of an effect than 100% DH/CH rate.

You aren't looking at it either as you're only considering the Inner Release window. Not consuming the beast gauge means that you will have your burst window no matter what happen and no matter what your beast gauge looks like. This also mean that you're completly free to use your gauge for a Fell Cleave every 6 GCD without any impact on your burst. Using the beast gauge for an Inner Beast is also something that absolutly doesn't affect your burst now.
You also now have the option for an "Inner Beast burst" in Defiance, which is something that was impossible before. Not saying that this is really relevant or that it'll be of any practical use, but more options are nice to have.

Plus it's not like PLD and DRK are to far behind WAR DPS as it is. It doesn't take that much of a decline for WAR to drop to the most useless tank.

Shake It Off it still extremely valuable. And for players of average skill level, the skill floor and ceiling of the job being drastically reduced will allow the average numbers to grow quite a lot. So I wouldn't be too concerned about WAR falling behind PLD and DRK.

On top of that, you're no longer using onslaught so much during Berserk Inner Release or between Berserkers Inner Releases, so your hate is going to be a lot worse without a ninja.

Don't forget that Diversion now last 30sec and cuts 90% of the generated enmity for the DPS jobs. Also, the opener for WAR is now extremely easy to perform and the burst comes quicker and stronger. If you are worried about enmity, you can simply Storm's Eye into Onslaught and even queue up with a Butcher's Block before going full on DH Crit Fell Cleaves... and then get a free DH crit Onslaught again (without Defiance).
Oh, and Unchained not sharing a cooldown with Inner Release means you will have it (Unchained) ready for every one of your Defiance pulls.
