Divine star healing people for 20k every 15 secs gotta love that aoe buddy. Not to mention unless people are stacked up its kinda worthless. Cascade is kinda worthless if people are stacked. Halo LOL long CD diminished returns too expensive to cast most of the time.
It definitely heals for more as Disc I would say and for holy it is definitely worth using stacked. I can get 100k plus crits from Divine Star.
