There is a little caveat to the way paid services work for goblins and worgen: either of them wishing to change races or factions cannot be in either Gilneas or Lost Isles.
There is no restrictions on on players wishing to change to goblins or worgen.
With two new playable races just on the horizon, many players have been asking when they'll be able to convert their existing characters into goblins or worgen. Paid faction and race changes will be available immediately once Cataclysm is released. Realm First achievements for leveling any class to 85 will be available in Cataclysm. However there will be no Realm First achievements associated with leveling characters of a specific race.
There will be a slight change to the way paid services work for goblins and worgen. Goblin and worgen characters wishing to change race or faction cannot be in Lost Isles or Gilneas; they must be elsewhere to initiate the process. There are no restrictions on race/faction change to goblin or worgen.You can learn more about our promotions and paid services here.
