Not saying 10x is bad, but every extreme rate server I've been on either burns out fast, or admins try to wipe often to keep people interested. In the long run, the people I've played with hate seeing all their hard word deleted. Maybe 4-5 people will stay after the wipe, the rest will leave. IMO, you wipe unbalanced servers, not healthy ones. Delete Tribes after 2 weeks of no activity and keep up with events and promotion.
