Post-patch Aim Assist is non-existent
After the patch that had to fix the 'stickiness' of the Aim Assist, it became basically non-existent at mid to long-range engagements. Even in CQB there are many times it's not even working. DICE, please add back the Launch day Aim Assist as an option. I know some controller players, had trouble because it dragged the Aim too much so if they like the new one, there's no problem. Just add options like: Strong slowdown (Launch day) and Loose Aim assist (the current one, that makes target switching easier). This way people have choices and both parties win.
