Just kidding, but by a curious coincidence the day of SOE downtime is the same day where patch 2.2 brings an extended downtime to World of Warcraft. Patch 2.2 has patch notes long as my arm, and as I'm not actively playing any more I find it hard to say which of these numerous small changes really have a big impact on the game. But the one thing that sticks out is the introduction of voice chat. Yes, voice chat is now integrated into World of Warcraft. Goodbye Teamspeak and Ventrilo!
Somebody please try it out and comment how good or bad it is working.
