I would like to see that Insurgency coop servers (6-8 players) get a separate ranking.
Now all coop servers are ranked the same as pvp servers.
Our server is ranked 10th place if you wouldn't count the pvp servers.

Feel free to post your idea in http://www.gametracker.com/forums/forum.php?site=1&category=164145 to see how many others are interested.

Please note, I recommend making a stronger case to support multiple ranking systems beyond that it would give your own server a better rank. For instance, you might argue that the two modes are completely separate in the game (just an example, as I've never played the game to know).
