I don't play WoW all that much, but I just wanted to warn you that in the time I spent on Lightninghoof (several years ago), it wasn't all that much of an RP server. I mean, sure Blizzard designated it to be an RP server, but the people I met on there, they made fun of you if you decided to try RPing something. From what I've heard though, Emerald Dream is a good RP-PvP server though, you could try making your guild there!
