To push is to clear enemy minions quickly so that your own wave advances down the lane. A strong push forces opponents to react, opens room for safe Roaming, and can create windows to threaten towers or set up a coordinated Siege.
Pushing is a core macro skill because controlling the pace of the lane directly impacts map pressure and objective timing. Champions with strong Waveclear can push more reliably, giving their team first move toward neutral objectives, early rotations, or deeper vision before the enemy can contest the area.
