It's not pretty, but it's effective. We used a two tank, two healer composition (Paladin/DK, Paladin/Druid) with an enhancement shaman (POV for this video) tossing out healing rain as needed, and our Prot and Ret paladins assiting with AoE (aka the Sparkle Pony heal) during the big AoE damage points.
Team Intensity standard raid comp -
Tanks - Prot Pally, DK
Healers - Holy Paladin, Druid
DPS - Elemental Shaman, Boomkin, Ret Paladin, Rogue, Shadow Priest, Hunter
Enjoy, and remember to watch it in all its 1080p hi-def deliciousness.
