Mattherson-east coast, easily the most active/interesting server with a very vocal community. Browse the outfit recruitment threads and try it out man. I guarantee you'll have a better playing experience.
I had no idea anyone else from here is playing! Sadly I'm with a clan on the east server. Be sure to slap BuzzCutPyscho and his zerglings around a few good times.
Oh yeah if any of you happen to find your way to the east cost server, give me an add-JimBeam
