Looks like character transfer is the phrase of the day. If you want to move to Rexxar and you're on Suramar, Draenor, Feathermoon, or Windrunner, you need to get busy. The transfer will end on Thursday, February 16. That's tomorrow.
Now, I'm happy for all of the people who get to transfer their characters to new realms to alleviate all of that clogging. However, I'd be extra happy if Blizzard could get off their duffs and fix the lag problem on Sen'jin which is a new server. It was unplayable last night and nobody wants to pay for a game that horks you off because you can't play it.
