Gunna have to respectfully disagree. Healers should be able to survive constant damage from a single dps as long as they line up their defensives with the DPS' offensive CD. Otherwise healers will be extremely frustrating to play outside of 2v2. Healers in 2v2 shouldn't die against another healer/dps comp until dampening begins to set in - or their dps should be the kill target during a CC chain.
