I've been looking around for a bit and still haven't found a solid answer;
Is the faction change service available before Cata's launch to switch from (ex. Human -> Goblin) ? Or will it be enabled some time into the expansion?
Thanks for clarifying! I should've put that in my post. Night Elf DRUIDS cannot race change until the day of as there is no other race option for them within their faction.
You can purchase a faction change RIGHT NOW if you would like, but have the option to not use it until Cataclysm launches, thus saving you the wait time for the race change to go through. All it does once it goes through is put an icon next to the selected character, but you don't have to do it right away, you can wait.
