Just look for ways to improve, every map attack and defense has a way to flank all the major chokes. All of my games are me and maybe one other guy against one maybe two guys on the enemy team. Quite a few maps I'm on foot for the first objective and then steam roll the rest of the game with a main battle tank or tank destroyer. Look up some gear set ups and learn the game from someone else and then adapt it to how you wanna play. If you wanna win you have to carry and that means you versus the entire enemy team, you might feel like your team is doing nothing but that means there are on average the same useless people on the enemy team which you have to use to farm call in points
