Found it this morning at http://www.multiplayerstrategies.com/. The dragon rider boss in Hellfire Ramparts. Works best with a pally or a warlock and I'll tell you why.
When you fight the boss, he's alot like Rend in UBRS in that you fight him and his dragon mount. Diffrence is you fight him first then the dragon. Kill the rider (sory dont know his exact name) then wipe on the dragon. SS or DI will make this tons faster. Regroup and when you get back, the boss will have reset but his LOOTABLE body will still be on the ground.
Start the fight and have someone go over and loot the dead one while youre fighting the live one. Then kill/loot the live one. You'll get two cracks at his loot table plus whatever the dragon drops. If you kill the second one before looting the first you will loose the loot from the first.
The reason this works is looting is bugged on him. You CAN'T all pass on his loot because you won't be able to pick it up. It MUST go to someone on the first need/greed roll. If its something you cant use, make ure it goes to the enchanter or that you understand someone is getting vendor trash.
3 locks, a healer and a tank could farm the living hell out of him since it only takes about 30 mins to get to him. You could POTENTIALY loot him 8 times in just over an hour with only one instance reset....WOW!
