Are they a thing? They sound fun and I wanna know of making one is worth it. Ty in advance 
I was thinking about them too, but since theyr only instant heal is on 6sec cd and other heal needs holy power, they might miss survivability
I feel like their survivability won't lack too much with some resil and armor, and their ability to get a full WoG in 12 seconds, and I was thinking 10 for the dodge potential. Do you think crit stacking would work?
