You just didnt understand this game to begin with, and I won't be sorry for you. Dps of healers isnt really that high to begin with since you need 3 - 4 dots and like 4 energy drains + same amount of Ruin 2 to kill a monk / dragoon / bard. Scholars are really good against melees / bards and weak against casters / tanks.

It is NOT unbalanced to have a healer that can simply be more than a punching ball. 8 healers groups have been defeated by playin cleverly, as in, swappin of outposts quite often and murderin the 2 other groups non stop. Healing a member of another group of your alliance is quite tricky ya know
