Starting up new servers won't do anything to help. Everybody knows GT, and plays on GT, despite their awful track record in admins, and their ridiculous player counts and map rotations. The only way we'll be able to change that habit, if needed, would be to remove GT from the serverlist again, or perhaps create some kind of anti-serverlist of servers that you can't join.
Obviously neither solution is a desirable one, but it's really a shame when a set of servers are driving a game more than the developer(s) is/are. Especially when said server admins don't seem particularly interested in moving the game forward.
