WoW has given us new heros/villlians as the game has gone on. sure the selling point to ALL of them excpet MoP was that we get to meet/ face an old baddy from WCII/III. really you have to blame it on blizzard's convoluted way of pushing the story forward. like they introduced a new Warchief who turned into a bad guy and went back in time JUST so we could have Gul'dan running around again.
