What makes a class needing Crit or Det or D.Hit in priority? (mainly about MCH)

Black Mage is one of the few classes in FFXIV that REALLY wants speed above all else because of how our casts are slower than the GCD.

yeah yesterday f.e. I was really surprised when fc mates talk about an 2200+ sks Samurai build as well... never thought it would be that important on any melee cls ever... but yeah good to see that those stats are not completely off like some others in the past
