I think that each region should have a fight club. I realize that maybe this kind of conflicts with the road map for private servers, but I think that the two can coexist. Fight clubs should be open to the public so that people can have 1v1s, This is currently a niche that is not met for a huge part of the Hawken populace that doesn't have access to private servers such as clan and tpg servers. Fight club is a great way to improve, settle beef, or just have some good fights.
TL;DR: I know that individuals may be inclined to host fight clubs once private servers roll out, but I believe there should be fight club servers separate from this.
