I'm active on pretty much every server...though, while I would recommend Wayfinder (the new German server) because its fairly, well, desolate, I also don't because that lack of people leads to a really shitty (read: non-existent) player economy, especially in the auction house. Which means, you're stuck being broke for most of the game, which is a real bitch.
But, should you decide on a server, I should be able to offer up my knowledge, power, and if on the right server, money, to help ya out.
