Warhammer Online servers

I have heard that there will be different types of servers for Warhammer Online and that you will be able to choose which one would you like to play on. What exactly will be the difference between the servers and which one will be the best one to choose? Thanks!

They say that there will be a ‘normal’ and a role playing server like in other games, for example World of Warcraft. As I have seen it on some forums, most of the people say they will choose the ‘normal’ server because they assume that the people who don’t know much about Warhammer and gaming generally will probably go to RP server and they’d like to avoid them. I must say that sounds pretty stupid to me.
