Hey everyone! I haven't played since the loss of data, and I was wondering, where is RP most commonly found? I have a character on Warsong, and I'm leveling an Alliance on...Neltharion (For all the cataclysm things). For WotLK I think I have a few toons on Ragnaros. Two ally and three horde.

Bumping because no answer and I really want to know =/

I can tell that there curretly 2 active RP guilds on Frostwolf alliance and also many players that are RPing
About Warsong or Neltharion idk sorry.

So the roleplay is restricted to Mists of Pandaria? That's a shame. :c
