I'm not arguing that something shouldn't be done here; CoH and WG in level 70 content are definitely borderline OP. But I hope blizzard takes into consideration some of the problems with our spells:

- GHeal & FHeal are slower(!) and less efficient than HL & FoL
- Renew ticks slowly and is less effective than the array of druids HoT stacking on a target
- The heal effect of Prayer of Mending, while undoubtedly good is out of our control;
- Prayer of Mending has a long cast time and unless the entire raid is taking large amounts of damage CHeal will generally have targets topped up anyway.

(No complaints about Power Word Shield & Disc Healing; I don't think that there's an accurate benchmark for the effectiveness of a Disc healer yet [Dmg Absorbed + Dmg Mitigated + Healing?] - I've healed heroics with no trouble, but in a raid environment everybody just points out the meters of course)

The problem is that if:

Shamans are great AOE Healers;
Paladins are great Single Target Healers;
Druids are great HoT healers;

You leave priests being able to do a little of all but excel at nothing and we know exactly who will be the first healer to be cut. It was exactly this way for priests in the burning crusade before late BT & Sunwell where raid-wide damage ramped up and we got a chance to shine.
