I don't get this game

I don't get this game, I do good but I lose anyways. There's no way to win anymore I feel as if this game is rigged. Everygame there's always that player feeding their ass off or the whole team is I can't even do anything about it because this game is a team game. This game is just plain stupid I don't know why I'm even still playing but it's whatever not everygame can be perfect I guess
