The greatest picks not in lane to counter Quinn include Kai'Sa, Kalista, and Zeri. These are all good at countering Quinn with high win rates over 61%. Even if these Quinn counter picks are not played in the same position as you, it's not a good idea to play her into any of these matchups. They will usually destroy Quinn.
Conversely, if the opposite team picks either Wukong or Rammus, you should strongly think about taking her, as she easily destroys these champions with win rates over 54% against both ofthem.
