why is aim assist still a thing

The argument from roller players is normally that we kbm players have privilege in movement and looting freedom.  Which is bunk logic.  This is like saying the athlete with natural talent that busts his * to be good has too much privilege from his genes and we should somehow push him down or elevate all the others to be at his level.  This is nothing more than catering to the lowest common denominator to try and level the field.  Participation trophies for all.

This is the way of it.  It is unfortunate, but the majority of players are roller now (something like 92%+ of pros).  COD is the same way.  I am also a PC player that has been complaining about AA for a long time in these games.  This is just the way competitive gaming seems to be going these days.  Making everything more casual.  AA saves people from hours of practicing pixel perfect flicks with their mouse and sensitivity of choice.
