I've been doing a couple of 2v2 with my warlock buddy and we are having some difficulties with healer / Melee composition.
While we are dealing quite easily the double DPS comp, Healer / Melee is totally insane. We are not losing to them, it is not hopoeless. To be honest, we are dealing with 30 minutes match because no one can kill no one. It's happening at least twice every arena session.
So any tips about this scenario?
