A couple of days ago, I was at Isle of Quel'Danas and notice this horde player hunter had a Devilsaur. The thing was that the devilsaur was HUGE and retained the elite status (golden dragon) around its portrait.
Since I was alliance, I wasn't able to ask him about it.
Was my eyes deceiving me? Maybe it was a npc? maybe a glitch?
I remember the players level was 70 and the Devilsaur was 65. I did beast lore on the Devilsaur and remember seeing it to be tame-able.
