TeamX Network is a project that's been in development for more than a year, and it's still growing. The goal is to keep improving the server and give players a better experience as it develops.
It looks like a survival-style server with PvE and PvP mixed in, plus raiding and roleplay elements. MCMMO is part of the setup too, so there's more progression to work on while you play. If that sounds like your kind of server, hop in and check it out.
