Don't worry about whether you win or lose in MLG Playlist... It is there as an individual skill builder. It helps you adapt to different playing styles. I am only a 40 in MLG. 75% of my losses are due to bad teammates and the other 25% is just being outplayed. It doesn't mean I will stop, if you keep going, you will improve eventually. However, in my honest opinion, the best place to build team chemistry is in Custom Scrimmage games against other teams.
