If you check your options, there's new server options.
(Server) Critical Hits - We all know what crits are. Enable/disable
(Server) Damage Spread - 10% increase/decrease on each hit. Enable/disable
(Server) [Class] Limit - 0-5/Unlimited
The class limiting is what I'm happy about. I can now limit my games instead of just yelling at people. I limit my games to two snipers, because we don't need more than two snipers on a team of 8. Of course, having the ability to disable classes presents problems, too. However, there's always plenty of games to find, so it's not that bad.
Who said the 360 doesn't get any love? :P
