Well, after being asked by a few people over the last several months if there would be a way to have a Co-op 'Rank' - I decided to tackle the idea. This is now working. If you're a Co-op 'h00r' - head to ...
to see how you measure up. If you want to know the basics of how the 'rank' is computed, check this post out. Basically it looks at how you've done on the top 200 Co-op maps played compared to how everyone else has done. Win a 'tough' Co-op, get more points. Lose an 'easy' one - lose more points. All Co-ops played in the tracked rooms (tourney rooms and ranked rooms) for the last 90 days count towards your Co-op 'rank' - but this is completely seperate from the MCS.
