Yeah, this is rather odd.
Though I remember WoW being quite unstable, especially before Burning Crusade , with regards to login issues, getting kicked out of game for absolutely no reason and just plain old constant emergency maintainance at times.... or you'd be playing and surprise! rolling restarts for all realms.
Wife and I and a nice handful of our friends left WoW for EQ2 and love it for the most part and I think Good Times are ahead. Burps do happen... maybe this is just a drawn-out-belch
