Yeah the rampart dragon boss is tough we killed him on our first try and I was tanking and some how I kept him from going straight for the healer. Then I tried again later as the healer and the dragon went right for me and by the time I got away to heal my heals went off to slow and the tank died before it went off. Its all about having a real healer for that fight or having the tank be able to grab the dragon and keep him from facing the group so healers like me with 3sec spells can get it off before he is dead.
