AST Anima stat allocation

[Taika]

You should not stack crit as an AST. Some suggest it is useful in Noct, but not nearly the same as a SCH and you will be in Diurnal more often than not.

Isn't crit really good for Diurnal AST as well because so much of the healing comes from regens and each regen tick can hit?

I don't play AST, but I've been thinking and talking about this with my healing partner who is AST and working on his relic. Seems like most information out there is controversial and I haven't been able to find the value of DET anywhere.
