Is it me or the Ai is bugged for healling. Like my healer always let my tank die and never cast healing spell except in one occasion. He start to cast healing spell like crazy only when tank is really low on health. And by health i mean health not endurance. Endurance being what keep you alive in a fight and health being unhealable by spell. :/ So i think they set the trigger wrong and what trigger the ai for casting healing spell is the wrong trigger.
