Quest in question:
Escape From the Lost City - Quest - World of Warcraft
I suspected there is some kind of exploit potential with the rewards from this quest. I always took the gold, which is contained in a bag and has to be opened, and historically that has had duping potential. I'm guessing the ramkahen rep is the same. RAOV came out with some stuff around this principle.
There are people out there who probably know more about this but are probably choosing not to comment. They may or may not contact you privately, but its not up to me to out them.
