I can only speak for 25's and 11 hc bosses experience so far (but ofc, some I did as Disc). Our potency is there, we are nowadays just to slow with our PoH's and our CoH is healing for 30k per target, EoL 6 seconds is just too slow to. We've become overrun by smartheals and absorbs so we can no longer show our potential. Most dmg patterns in SoO don't suit Holy too well this tier either. Spread random dmg is common with bursts on the raid (being healed up in a couple of sec), and Chakra don't go well together with mixed AoE/ST healing. If you look at previous tiers, you can see they had Chakra CD in their head designing dmg clearly. Not the case here usually. LFR can be much more fun to heal as Hpri, if there are bad healers in the raid, than heroic raids. Too bad, cause finally we got the mana to /flex (funny thing is I reforge away spirit and have less now than in t15).
Also, we need "utility" badly. Something above our healing done.
But atleast I win every time, on the Overhealing meters
So consensus? Holy is to prefer when underhealing stuff where you still wont need absorbs or extra dmg.
Just waiting for 6.0 now. Besides revamping Holy Priests, I do hope they do something about every other heal in the game now being smart.
Btw, where did the Holy Paradox thread go?
