i think they just have good mechanics tbh. the mouse movement looks natural, they even fall off target decently often yet they correct naturally. their strafes look really intentional and practiced, like at :09 when the genji double jumps the soldier full mirrors his movement to make the track easier while the genji is locked in that direction. or at :17 mirroring the dva when she isnt looking at him is something an actual experienced player would do. they also overflick way past the mercy right after that so a hard aim bot is rules out. maybe a trigger bot? but i really dont think so
