Quest in question: Escape From the Lost metropolis - 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 individuals out there who most likely know much more around this yet are most likely choosing not to comment. They might well or might well not contact you privately, but its not up to me to out them.
