Playing against Lee Sin
How to counter and exploit weaknesses
Watch the bushes early: Lee Sin often looks to invade your jungle at level 2-3 thanks to his dueling power.
If Lee Sin misses his Q, he loses everything: his engage, damage, and mobility all depend on landing Q. Play aggressively during the cooldown.
Stay away from your carries in teamfights — Lee Sin looks to kick a target toward his team with R.
He scales poorly into late game — if you survive his aggressive early game, you'll likely have the advantage after 25 minutes.
