If you are an average player, don't bother. One person doesn't win the match. I just had 8 losing matches in a row, they don't keep the teams fair. If your K/D is less than 1, you should be put with players that are the same as you. If you get slaughtered, match after match, it's time to look at a different game. Nobody likes to lose 8 multiplayer matches in a row or get slaughtered. I can understand why people leave matches. I hope they make some changes soon or I will definitely find a game that is more fun. I have spent a lot of money in past games, I will not buy any upgrades in MW3 unless changes are made.
