New VR strategy

We start off by sending two hunters to the outer ring, when we start they run opposite of each other around the room drawing the arcane bombs away from the rest of the raid...which dps's and heals from under his feet. Now this method is rough on healers, however we stack the deck using a dedicated healer group containing 3 resto shamans a holy priest and a shadow priest. The shamans use stackable totems and they all heal through the ground pounds with no trouble.

The main things to keep in mind with this technique are to ensure everyone but three tanks (and the two hunters, though one can do the job as well) are directly behind VR at all times. Have plenty of heals and mana regen to push through the ground pound damage (arcane resist gear helps here). Have the hunters keep misdirect up on the tanks as needed using whatever attacks they can do while moving, stopping = hunter death. Have all raid DPSers keep their eyes on their threat and do NOT exceed the tanks.

This video is in real time, so you'll see we get him down well before the enrage timer, as long as you have the area heals and mana to do it this way, I'd say it's by far the least difficult.
