After reading this thread, it occurred to me that I've never seen a single Alterac Valley match where anyone summoned Ivus or his Horde counterpart, Lokholar the Ice Lord. I started playing at the beginning of The Burning Crusade, and I get the impression that the days-long AV matches where these summons and special events were common largely ended in classic. But you know what? Now I really want to see what kind of havoc one of these bad boys could wreak on a gloriously unsuspecting enemy, and it's vaulted to the top of my WoW To-Do list.
So what's on your WoW bucket list? What haven't you done in the game yet that's on your list of goals?
