Yeah, that could be said of ANYTHING. Take basketball... You take the ball, go to the other end of the court and put it in the hoop. Easy, right? Now what happens when the other TEAM is using their teamwork to block you at every turn? You need YOUR team, right?
That is exactly the Battlefield dynamic, it's all about struggle for control, like most MP games, except where BF is different is that if you use Teamwork, you can basically never lose your defence. You keep one guy spawning squad mates, you can keep that defence up, or your offense. You have that one medic on your squad that keeps reviving the rest of the squad, you can keep it up. You get an engineer to ride in your helicopter to keep repairing it, while you ferry guys over to the objective and drop them off, or keep a tank up and running until you've destroyed the base... i mean, the majority of the gameplay elements in that game are built around teamwork.
The fact that you value success on either winning/losing shows you do have a classic MP attitude to it. This isn't COD or Halo, where you look at a little score to see who is winning, Battlefield has always been about more than that. I mean, it's essentially what it's name is, a 'Battlefield' simulator.
