I say, Stick with the tank. I usually try to follow people, but if they are OOR because they ran off all willy nilly, they are just going to have to die... >.>. I am sorry, tank is priority #1 in my eyes.

I don't Use any DD spells, Just in case i have to go berserk on the healing. I think you did all right, Where was you're healing support? Usually there are two healers per group.
