Tracking
An aim style for sustained-damage heroes: keeping the crosshair glued to the enemy's movement.
Because OW2 has a long TTK and high mobility, heroes that generate value by landing continuous fire — sustained hitscan like Soldier:76 and Tracer, or Reaper — spend long stretches unable to take the crosshair off target. The advanced standard is not simply following, but predictive tracking: reading the reversal in the enemy's strafe and already having the crosshair where they are about to be. Where flick is the "swing" for single-shot high-damage heroes, tracking is the "stick" for sustained-damage heroes — the combination of which hero you are on and the engagement range decides which aim style you lead with. Some situations demand both, but whether you switch consciously is what determines your accuracy.
When fighting at close-to-mid range on sustained hitscan like Soldier:76 or Tracer, follow the enemy's strafe while predicting the direction of the next reversal and placing your crosshair ahead of it. At ranges where the strafe is small and readable, predictive tracking returns damage consistently.
Carrying tracking habits onto single-shot burst heroes (Widowmaker, Cassidy, etc.), dragging the crosshair instead of swinging wide, and missing by exactly the gap you never close. Or chasing the enemy's strafe so you are always trailing it, drifting off on every reversal and wasting shots.
