I think there should be less points applied to a freestyle win. Maybe a multiplier of 3/4. Freestyle games are fun and what not but they are gamed so easily. Some players only play freestyle games with a select number of team mates who know how to game and work the system. So what their score actually reflects is how well they can play the CC system rather than how well a strategist they are.
I think this would reduce the amount of grey-area cheating that goes on in the freestyle games. Of course people can still play freestyle for the fun of it, but let's face it, it takes a different set of 'skills' to win at freestyle then it does sequential, so why should both skills sets be award the same amount of points, when one 'skill set' involved annoying and deceptive game play.
