axon you can have a character on every server if you wish. If you aren't big into PvP then avoid the PvP servers. Thats usually where the ass clowns of the MMORPG community usally find themselves. While there might be a few good players on a PvP server I have yet to see any, and definatly no community building on PvP servers.
I think you'll find the same thing I did though, once you get to the high level you'll need a guild to do anything interesting. Since there is (or at least was) a fairly low limit on the number of characters in a guild you'll find most are a pain to get into (at least the ones worth a damn).
Being guildless at high level sucks.
I say play it until you get bored of it since you've already bought it, but don't expect it to last more then 6 months or so for you.
