Playing against Quinn

How to counter and exploit weaknesses

1

Quinn is squishy and short-ranged for a ranged champion: gap-closers punish her once her E is on cooldown.

2

Her E has a single use (dash back): if you bait it, she has no self-peel for about 12s.

3

Don't let her roam: ping MIA when she leaves lane because her R makes her extremely fast.

4

Tanks with gap-closing CC counter her after level 6: Malphite R, Ornn R, etc.
