AST, Underpowered?, Potential changes, and you.

[Eudyptes]

That still wouldn't work, because by casting Aspected Benefic you are replacing a Benefic cast guaranteed to heal double a normal Benefic over the duration in Diurnal (790 total), vs. trying to get a crit shield isn't guaranteed and can't be relied on.

Well, Diurnal and Noct don't have to be exactly identical for A.Bene and A.Helios potencies. Noct needs a boost, but it's fine if diurnal ends up doing more considering most of the healing is done through HoTs. Noct is instantaneous and less prone to overhealing. Choosing less potency on non-crits with a higher potency on crits vs a consistant in between potency seems about right to me personally.

CDs in general need a massive reworking, though there is a limit to how much they can do.
