This is quite possibly my FAVORITE fight in all of ICC. It's a healer fight, and I'm not talking about a high tank damage fight either. The healers are what 'HPS' the boss to get it to full before the raid dies or the boss dies. I'm one of my guild's core healers, and when our pally is out sick, I stay on the boss the whole time. You'd be surprised what a resto shaman can do single target, no overheal.
