To Amend on Jaxsons method: a much easier way is to simply:
Pull both of the Death Talon Wyrmguard 3-packs before the Drake/Chromaggus rooms.
Kill two from each pack, just make sure to leave one alive from each pack. Marking helps.
Check for phat loots.
Aggro Ebonroc and run into Chromaggus's room. Have him punt you up onto the ledge behind the lever (dont pull it).
Once you're on the ledge, wait a few seconds and they will all reset.
This will allow you to farm 4 Wyrms per 'reset'. Should have your goodies within minutes!
