League of Legends
Lee Sin players popularized ward-hop plus Dragon's Rage repositioning to kick enemies into their team. It is now iconic tech, but it began as exploit-like mastery of movement rules and instant inputs.
Many champions have or had cancels that compress casts or hide parts of their spell windups for unexpected burst. Riven is the classic example of this exploit-like execution layer.
Some champions could farm between enemy towers to deny wave interaction and manipulate pressure in ways the lane system did not clearly intend. Singed proxying made the tactic famous.
Players can stand at the edge of brush, terrain, or fog thresholds to briefly gain vision without fully exposing themselves. These pixel-perfect vision checks are treated as exploitative by many players.
Body-blocking with minions can trap targets, break last-hit spacing, or force champions into awkward routes because of League's pathing rules. It is a persistent collision exploit of lane states.
