The test realm patch notes (found here:
http://www.worldofwarcraft.com/patch...atchnotes.html) indicate that warlocks are going to be able to redo their talent builds for free in the next patch.
Needless to say, as a 49 warlock who desperately needs to redo her build, I'm completely stoked.
I also want to know why they keep adding flight paths for Horde when Alliance has far fewer flight paths and some really idiotic connections. Uggh.
