Quick question about teamwork.

Why does it seem that the only way 343i knows how to make teamwork in a game is to make one person so useless that he requires a teammate?

Rather than encourage teamwork in other ways, 343i is making it so a person has absolutely nothing at his disposal, making teamwork the ultimatum rather than haveing a good mix of personal and team skill.

Not to mention the kind of teamwork they are promoting is the lowest form of teamwork, teamshooting.
