BREAKING NEWS! Please click the read more link to learn about the changes coming to the next Warlords of Draenor beta build!
Blizzard has confirmed the next build of the World of Warcraft: Warlords of Draenor beta build will wipe all characters currently testing.

In preparation for the next beta build that is planned to go live July 25, we will be doing a character wipe on the beta realms. Once the new build is live, you will also notice that the realms have been renamed, and that you will be able to create level 100 PvP and PvE characters. For more information about the new realm names, check out the thread Lore recently posted here.
EDIT: Apologies for any confusion; characters are being wiped from the beta realms today.
