Aion's Claric healer was a fricken monster wearing chainmail armor with twelve or more deeps skills! Where is this healers only heal nonsense even coming from? I do not understand.. I have always done damage on healers in every game I play them in even Overwatch.

There is something most satisfying about Lucio booping someone to their demise or unleashing five Zenyatta orbs directly into the cranium of one unsuspecting soul.

Healers are within the "support" tier or considered this in most places even within table top. Support doth not mean "healbot" it means "support" which can be accomplished in many many ways. To give example, if the thing is dead no healing is required and thus you have supported the party.

Aye you did indeed queue as the healer which is your primary function within the group. It is not the only function within the group. If the intention was for healers to only heal then Astro would not have cards and no healer would have percent damage reduction abilities. Can you imagine what might occur if tanks adopted similar mentality? "Welp! My job is to hold aggro so I will only do enough damage to sustain threat, I suppose."

It is not unreasonable to desire complexity beyond push the big heal button after the big damage, and after seeing some of Sage it appears there is some light at end of tunnel. Square must have noticed something or Sage would never have been given a skill that heals through dealing damage. It even gets a fricken engage! That is smexy as all heck!
