Crit damage buffs should be reworked
Adding more auto-crit abilities to the game devalues these abilities. You can already see a palpable difference between how much a Warrior and <any other job> benefit from abilities like Chain Strat, Litany, etc. The Samurai changes only highlight this issue again.
In my opinion, these abilities should be changed to affect critical damage rather than critical rate. Keeps an element of RNG, prevents a distinct lack of synergy, and isn't just turning them into another raw damage % CD. Their identity remains crit oriented.
Otherwise it just seems odd to me that a point was made to align everybody's buff windows, only to keep and then exacerbate an issue of some classes and buffs not playing nice with each other.
