So i was farming for the netherwing drake and the last quest [In service of the Illidari] i just can't pass. I need to give te quest to the Overlord Mor' Ghor but i can just kill him even though im exalted with them. Please help me i was farming it for a long time and now that happens and i really like that mount if u have any idea put it in comments.
I had the same issue, but the thing that fixed that issue for me was to mount up and move away from the island so it won't be visible, then come back. Also you have to have that buff where it turns you to an orc like them.
