Ladies and gentlemen!
at the current moment, you can create both horde and alliance factions on the same pvp-enabled server! Unlike before, you now can!
Im not sure if this was implemented or not, but you can right this very moment and it was not included in the patch notes and as far as i can remember i have never been able to do this.
Can anyone say WIN?
Pics or it never happened right?
So take it easy and enjoy
Edit
nevermind, this is intended and was posted earlier. Sorry >.>
