This is for ANY Warrior, DK, Druid, or Paladin with an average ilvl of 329 or higher, you can sell tank queues to people even if you don't tank at all. Spam trade with something like "Selling instant heroic queues 50g per person in group", or something like that, once you get your group, queue as tank and enter dungeon. Once inside the dungeon alt+f4 and wait 5 minutes before logging back on. You will not have debuff and you can repeat.
