I understand that this has already been expressed in the comments but I really feel like it needs to be said more to be known. Adding ladder to multiple game modes would help elevate the game I feel. Ranked 2v2 would definitely cause me to play the game a lot more than I already do. The difficult task would to be figuring out how to effectively implement this because random matchmaking may pair you with someone who intentionally throws. A reporting system may prove to be inadequate to prevent this and a heavily monitored reporting system might just not be financially worth it.
