Free transfers for select realms
I should probably clarify that by saying very select realms, as in two. If you happen to be on Aerie Peak or Warsong, and would like to leave due to the congestion (or any reason really), Blizzard is offering free transfers to less crowded servers.
If you are on Warsong, you may transfer to Zuluhed, Ysondre or Dentarg. If you happen to be an Aerie Peak resident, you can take advantage of free transfers to Jaedanar, Tanaris or Ysera. Transfers start on Thursday, November 9th at 3 AM PST, and run through Wednesday, November 15th. You must transfer your toon between the hours of 3 AM and 3 PM PST.
Good news for the folks on those two realms who have been experiencing incredibly high queues. And maybe the destination realms will benefit from an infusion of new players. Or maybe they'll hate it. Either way, the transfers are coming.
