World of Warcraft players will no longer be required to log out of the game in order to change details about their characters. Several once-online only services have been moved directly into the game client via the in-game store. This means that players will be able to change appearance, faction, name or race directly from the shop interface on the character-select screen while not being logged into the game itself.
- Appearance Change—Change your character’s appearance, including their gender, face, skin color, hair color, hair style, and name as desired.
- Faction Change—Switch your allegiance from Horde to Alliance or Alliance to Horde.
- Name Change—Change your character’s name to something a bit more.
- Race Change—Change your race to one within your same faction.
