Any time i was near the cave, i eventually got healer agro when a couple mobs broke through the lines and would just about one shot the healer so i tend to stay away from that side, but i'd def try again if i could find a place without the ice.
What do you do when he calls a target for the frostwyrm? doesn't the aoe freeze and stun everyone for 6 secs?
