If you play fps games to feel good about yourself why play halo? You don't really flick and you definitely don't spray control or burst really. Anyways bullet mag wouldn't change the fact that you still have to aim and track the target. At close range you probably wouldn't see a difference. It would just allow you to fight better at range. With MNK you can put your crossshair on target and miss shots if they are far away. If you put your crosshair in the same position with a controller you would hit more shots at the same range. That has nothing to skill or your aiming ability. It's down to the inaccuracies of shooting. Bullet mag on MNK would make it so there is less of a difference in this scenario between inputs.
