Aimbot: hitscan and projectile need different settings
For Cassidy, Ashe and Widowmaker the aim tracks directly: pull to the head, capture radius, smoothing. For Hanzo, Pharah and Genji prediction kicks in — the projectile takes time to travel, so the point is led along the target's movement vector.
All of it gets tuned around the killcam. After dying, a player watches the last seconds through the killer's eyes, and reports come from exactly there: a sharp flick across half the map reads instantly, soft tracking inside a narrow angle does not. Working configs dial the pull speed down, not up.
