It has already been said but when I tanked Titan Hard Mode on my WAR I brought 3 healers. It was a FC run and everyone knew what they were doing throughout. We wiped a few times due to random dps dying, however no wipe was due to me dying. With 3 healers and me timing thrill of battle and Inner Beast to every mountain buster I could we made it through. Granted it helped immensely that I was able to parry 2 consecutive mountain busters which was pretty epic when the healers were strapped for mana.
