Outside of an expansion?
Lily is absolutely not enough to heal DT aoe, the usual aoe damage in DT is ~50% max HP, this means ~800 spell potency. you can reach 800 spell potency only with cure III + primary indulgence, and PI has 60 sec CD, while the aoe are more frequent.
This means I cannot simply spam glare and use aff. rapture when I see a "less than 100%" HP bar.
It's been a long time since I've been forced to use Cure II and not Aff. Solace.
In ARR we had aero I , aero II, Holy nova, Stone
In DT we have dia, Afflatus misery, Holy nova, glare, assize, sacred sight.
