What is the reason to nerf healing damage so badly that my 66 SMN kills faster then a 70 AST with an i290 weapon? I did not even DT and she did not use balance.

The level 70 AST has way more stats then me as well in everything, and yet I kill faster (do more DPS) This means SCH is really hurting and I can feel it big time when I do runs. Healer DPS is too low, I want the old cleric stance back
