Switching factions in the World Of Warcraft gaming sphere is one of those things that can start an Internet flame war. Adding fuel to that is the fact that WoW is now allowing you to do that for $30.
So in practical terms, if you’re a badass with ties to the Horde, you can forfeit your god-like status for something decidedly less sexy, like something on the other side of the fence. And if you’re part of the Alliance, you can pull that same crap.
The talks are that Blizzard is also planning on implementing a similar system to change character race. Faction and class would still be kept. Sex changes are off limits. Hopefully.
