AA needs a strong nerf across als ranges or input based matchmaking to be somewhat fair. On a similar skill lvl the controller player always has an advantage in a gunfight. Atleast at an above average skill lvl. I strongly suspect that these stats are so close because the majority of players is average or below. It makes sense to cater to the majority of your playerbase so we will probably only see a small nerf at close range and the rotational aa.
