Blizzard announced the opening of four new realms where you can start a fresh community:

Aegwynn PVP
Akama PVP
Chromaggus PVP
Draka PVE

There is also new transfers available:

Tichondrius > Kalecgos
Illidan > Ursin
Sargeras > Detheroc

These transfers will be available at the normal time, 3:00AM-3:00PM PST, until December 7, at 3:00PM.

Realm-to-realm character transfers are offered in order to alleviate queue times and overpopulation. If you’re not satisfied with your realm’s performance, moving to a realm with a lower population can make your play experience more enjoyable.
