At the minimum, I dislike that we have a mode where animations dictate when the damage is dealt, and yet there are stage hazards which are dictated by the cast bars like in PvE. It's a bit disorienting.

At the worst, we now have tooltips that are less accurate because they don't explain when you need to activate the button to actually get the effect.

Most animations also weren't designed to be responsive or snappy with the timing of your presses, they were designed to be flashy for job action trailers. Not really sure there's an upside. At best, it's just different from the previous version (and the rest of the game).
