Being a "lone wolf commando" makes you look both stupid and like a total dick in team-based games.
Sure, there's the trust issue [this one time, first time playing Halo 3, some guy tried to drive me off a cliff], but if you play with sensible people who are there to actually have some fun, then being helpful to each other makes for a much more entertaining experience.

I guess you are the lone wolf kind.
