Whoo! 2.3 Should be on the Test Realms soon (if they aren’t already there). Posted in the normal place ( http://www.worldofwarcraft.com/patchnotes/test-realm-patchnotes.html ) are the patch notes.
Some interesting stuff that we didn’t know already:
Greatly increased the radius of the Drums of Battle, Drums of Restoration, Drums of Speed, and Drums of War.
Removed the casting time [...]
