I remember clearly, I healed him during the run, and we later did SM which he couldn't manage on his own without doing small pulls, so he brought another guy (T2 Warrior) to help make it faster. I had to heal the Mage to keep him up in SM. (Edit: I had to heal him to keep him up so we could do quick runs, not because a small pull would kill him otherwise)
Elites hurt. They did at least double damage vs a normal mob.
