Do something with taliyah please
She's challenger tier in plat+, diamond+ and master+ on lolalytics. She's OP tier on op.gg. She has a high play rate and win rate.
I honestly never had an issue with her before the waveclear nerfs, but patch 8.11 just shoved more damage into her kit (mostly through increased damage on subsequent rocks), making her downright cancerous to play against.
