Until we have more than just heals then healers will do dps. We should have enhancements, enfeebling, debuffs and buffs to keep us busy outside of just healing. The closest we get to that is SCH and AST. Healers are missing spells like phlanx, shell, elemental spikes, blind, paralyze, Barspells, blink, haste, en-spells, boost stat spells etc.

Cleric is a stupid ability and should be removed I think it was lazy to not just let our spells be based on mind.
