Get hit a lot. Buff the party. Blocking is your friend. Your job is to keep the adds off the ranged attackers or keep an AOE Boss focused on you. I like abilities that knock enemies back allowing you to heal or change position. Unless I am totally doing it wrong, then someone will correct me here :)
I also have a Level 60 weapon reward that when equipped says I must equip a weapon. Guardian Fighter. I have since found a better sword, but still bugs me. Dax Razor
