"Games like Overwatch had Aim Assist on PC during the beta and was subsequently quickly removed after it was brought to Blizzards attention about using the XIM4.
There's a reason no competitive FPS has Aim Assist, it's not just because of "PC Master Race can't handle getting booked by controllers" which i see pop up every now and then. It's because people can literally get a free aimbot that is undetectable with a keyboard and mouse. It has NO place in PVP games."

Destiny 2 has built-in aimbot basically and when used with XIM4, you have undetectable serious advantage against controller and k+m players. Aim assist needs to be [b]tweaked[/b] or removed for PVP side of the game.
Edit: What I mean by competitive PVP - Competitive Play mode and Trials of Osiris/Trials of the Nine. I wasn't talking about ESL. I don't want anyone to have advantage over me when playing those two game modes.
