All this game does is freeze

I have had it with this game and its freezing. I just about had a LASO mission complete and the freezing of MCC rears its ugly head. Is there anything to do on this game anymore. Matchmaking is unfair teams everygame. The ranks are pointless cause you play against ranks 20 above or below you. You never get to play Objective gametypes. Now this!!! Cant even play Campaign. This game is a colossal failure.
