I think that this game lets ourselves out in our fantasies to role-play enough even if we aren't in a said RP server.
It doesn't depend on which server you are, but on the people's will to make some fantasy RP moments, so it doesn't matter at the end which server you choose, but with who you're talking to. You can be together with who you like and RP with who wants. In this game it's a win/win case =)
