My problem with this game is: no matter how high I turn up my controller sensitivity, my aiming feels extremely sluggish. This game has a “feature” called “Aim Acceleration”. This means you need to hold the stick in a direction and in order for you to reach max velocity, you must reach the max acceleration first. Altering deadzone and maximizing the acceleration does not help. I do not want to have to buy a desk, a mouse and keyboard to play this game. This ruins the experience because competitive players are only going to use mouse and keyboard(“mouse acceleration” can be turned off). This is a fundamental flaw in the games design and hurts players that want to play halo with a controller(the way it was intended to be played). My only wish is that an option is added to remove this “feature” for the controller options. That would make the game feel alot more fluid while playing with a controller.
