Had to try, with my pally prot, went to Onyxia and solo her in 57 min. Hell pain the air phase, but still doable. I know many of you already done it, if not, go and give it a shot. It feels so cool. When i say on guild "woot just killed Onyxia Solo" all around were Wooo amazing... ubber. Was the symbol of power come true.
Anyway, wish we can have a title like "the Dragon Hunter" but meh.
Good Hunting.
