Much as I dislike the two minute meta (and boy do I), I think the easier way to cut through the tangle of issues is nerfing the crap out of crit. It's become such a dominant stat that everyone wants to meld it. It's so strong that it beats out every other option for even the jobs that traditionally like skill/spell speed more. Even worse, it's the king of RNG stats. Combine that with the high potency finisher moves and it's a recipe for a large chunk of your damage being completely out of your control. So much of your damage comes from crit luck in buff windows. Every time I watch my auto attack eat that direct crit roll for 40 overexcited damage before Resolution hits for a limp regular hit, I know I just missed out on 30-40 thousand damage that had nothing to do with me.
