I almost never use my priests for healing. Sometimes Consecrated Ground is handy, but I don't use it too often.
Their buffs and prayers however make the game so much easier that even PotD gets easy (if you know what you're doing).
If you have a priest you don't have to bother with defensive talents or abilites. Why putting points into Aegis of Loyality, Bull's Will or Body Control or whatever if the whole party can be immune with the casting of a prayer?
What makes priests so strong in PoE (besides their really powerful damaging spells in higher levels) is buffs and prayers, not healing. In fact, I consider the druid or a Kind Wayfarer to be the better party healer (Moonwell and Garden of Life are really strong) and the paladin to be the better healer for individuals (Lay on Hands). Besides that, there's Ancient Memory + Ancient Spirits, Constant or Veteran's Recovery, which is really good - especially if you combine those with the relatively new healing bonuses you can get from survival (+20% for 2 points and then +20% every 6 points) and items (St. Borragia's Tears: +15% healing done, Belt of Bountiful Healing, Fulvano's Amulet, Maneha's Armor: +25% healing received). This stacks pretty nicely with other self heals like Savage Defiance and also Second Wind so that I rarely need healing spells at all.
