Healock was funny to play when he could heal through dealing damage, now with that stupid boring mechanic he can't do neither heal teammates as a cleric do, nor deal decent damage. I think the class needs rework, especially the healer path.
that's not true actually, warlock can't be "dps" or even decent healer/tank(not close to cleric, by the way cleric is the most powerful dd right now/or healer).
I think they should add an option with the scaling (to 14k ilvl for example); remove pet's boons and bring back healing depression, tenacity; give some rewards like 12k ad for pvp with no scaling, 8k ad for pvp with scaling.
