This has to be done at 57 or 58 ( cant remember what level you have to be to zone into Outlands).
The release of The Burning Crusade has introduced many new dungeons, one of which is the level 60-63 dungeon Hellfire Citadel. On my server theres about 100 level 60s walking HFC. Simply go to the Ramparts or Bloodforge instance portal and duel. As soon as the duel begins, MC him and jump him off the side. If its something like a rogue or mage then u have to be real fast with the cast otherwise you'll lose and they may not want to reduel. I spent 2 hours yesterday jumping Hordies (and some Alliance) off of HFC. This may or not be enough to kill him but it'll usually say he fled and u won. Also if you aim it right, you'll be able to jump him in to a crowd of 61 to 63's. Wigh half of his health left he will most likely die
Have Fun
P.S. didnt know whether to post in Scams or Exploits so i posted in General
