Hey all. I have been haunting these forums for a bit now. But finally decided to post. Has any one confirmed whether or not you can still find Terropene after the zone phases? I haven't seen any comment on that except for one. But no one else has said a word. Thanks a bunch.
I can't say for certain, but I strongly suspect that since the area he spawns in (by Sulfuron Spire) is not affected by phasing as you complete Hyjal quests, that Terrorpene's spawn is not affected either.
