Cataclysm Classic - Halls of Lightning Protection Warrior Farming.

Runs are roughly 3 minutes give or take some, can be fairly annoying with the knockbacks. This typically is about 100-150g per run, of course give or take some, depending on your server. Pure DPS gear, survivability/healing spec, no raid gear required. Have Tailoring on the character you run with for extra cloth drops, have an Alt character that can disenchant the wotlk BoE blues/greens, vendor everything else.
