Head your raid (up to 10 players at time) to LBRS and Mind Control one or more Scarshield Spellbinders (you can find them just at the entrance under the bridge), at this point provide all players with his +81 Fire resistance buff. The buff lasts 60 Minutes, and is on a 30 second cooldown. This trick was initially thought to be a bannable offense, but it is actually perfectly legal and ok to use.
