So something that just been wondering, I noticed that Tanaan Jungle is greyed out in the Map, meaning its left undiscovered, and shows as lvl100 area. We went to one small part of it at the start (The Dark Portal) but the rest of it is blocked off. Also seen people in the Beta exploit their way way though to that zone, seeing lvl100 mobs and whatnot.
Was this ever confirmed to be a zone in a later patch, or a reason why it was left out?
