I just jumped in between master chief collection, battlefield 4, call of duty aw and titanfall. Halo 5 has something fundamentally wrong with the aiming. It has nothing to do with aim assist. There is a large zone on the right stick that when aiming down the sights is a slow and precise movement. It’s a single speed, and any movement outside of that zone and you are instantly thrown into your sensitivity speed. Changing your sensitivity has no effect on the speed of the “precision aiming zone”. There is no smooth transition between aiming speeds. Aiming down the sight and trying to line up a headshot at the pre determined deadzone speed isn’t fast enough. And moving outside of the zone causes you to overshoot your target, causing a back and fourth battle to catch the target’s head. I can’t play like this, it has nothing to do with aim assist. Play any other shooter and come back and play halo 5. Something is either wrong, or if this is an intended mechanic, whoever thought this was a good idea needs a bullet to the head, in bf4 or some other shooter because it sure as hell isn’t happening in this game.
