Are you bored with being a good guy? Looking to turn into a total *^&%*%& and switch sides to the Horde? Blizzard will finally let players become *^&%*%& with an upcoming feature. No word on whether this will cost any money (more that likely it will because hey, it’s a MMO), but you will finally be able to make the switch to a similar character of the opposite side. All of your levels and weapons will make the switch.
Blizzard notes there is still work to do and failed to offer a date when this functionality will go live. There seems to be some apprehension on the official forums, but most seem pleased with the decision.
