Face this earlier this month

Using my UBERTEAM (disc/prot pall/hunters) I was barely able to get my tank to survive getting there (sending all the pets ahead of the group and with the priest back shielding the tank on CD). The boss himself is weak enough to be one-manned with a prot paladin in full heirlooms but I'm afraid I did this dungeon twice and didn't actually have a clean kill either time.

You might also try having the tank grab a shield and the priest, and then normal follow and perhaps the priests shield would protect the dps more?
