CM's AF is way to accurate.
Image you are a BAR gunner, now look at a grove that is 200m away from you. Image the sergeant shouting, fire at the woods. I see movement at the left side of the woods.
OK , so you are going to shoot left side of the woods, but what is the exactly aiming point? You probably just fire a short burst here and there. Spray the bullets in an area that cover part of the woods. So area fire should have longer reaction time and larger dispersion。
Hopefully in the future we will have a separate command that cover the area fire.
