Wait...all this thread for a 3 to 4 month old build, without seeing and playing things yourself and based on the first MSQ dungeon being completed by Ultimate raiders with no healer?
Even in roulettes I need to heal or people die, not everyone plays well all the time. Yes dps rotation is simple but you weave heals throughout. If you just want to dps play a dps. I cant see the issue. Sorry.
