Here's what you do:
1. Set up a group with someone that is offline. (IE invite another account's char and log them off or use actual people you know who are willing to stay grouped.) Set the looting to Master Looter.
2. Find the Time-lost Proto Drake flying around in Storm Peaks. This requires quite a bit of patience.
Note: You can do step 1 and 2 in any order.
3. Tag the Time-lost Proto Drake, but don't kill it.
4. Advertise in general that you are selling his loot to someone for >insert your price here< (10k+ is advised).
5. Invite whoever says they'll buy first.
6. Have them pay you first, then kill, master loot to them, enjoy.
