Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello Tomblerone here!
I just wanted to ask if there currently any method to change my Faction?
I would need to change from alliance to horde since i got lots of IRL friends playing on the horde side.
Please let me know if there is any way i would really love to be able to change/pay for this opportunity!
After all its alot smoother to play with your buddies than to get ganked by them!
Anyway thanks and have a nice day!

There is one method available to change faction: Reroll.

Faction change was implemented in TBC just saying.

"Faction Change" It would be nice to implement it.
