You know... I kinda like it better when my allies are controlled by the computer.
More immersive.
Of course i also like games where it's hard to be "The defining factor" in a game. IE you can really help your squad when, but they could screw it up still... or you could really screw up... and your team could still pull it off if they're better matched.
Sadly so few games are like that... where you play a role... instead of THE role.
