Today Blizzard finally launched a service that allows World of Warcraft players to change their player faction. However, unlike most sex changes which can cost thousands upon thousands of dollars, players wanting to "switch teams" will only need to shell out a whopping $30 USD before applicable taxes. This cost covers a single faction change for a single character.
This FAQ lists all the pluses and minuses of changing factions, including limits associated with amounts of gold, the character's new origin location, and restrictions of characters pending a name change or re-customization. Players can change their character's faction through the Account Management page; the interface also allows them to select a new race based on their class and new faction.
According to Blizzard, players will be charged immediately once the change is confirmed, and the process cannot be cancelled. Additionally, characters will not be able to revert back to their old faction after the change takes place. Blizzard also said that active mail and auction items will prevent a character from switching factions.
Unfortunately, players cannot use the new service to change a race of an existing faction. Blizzard states that a Race Change service will be available in the near future.
