Just read patch note 9.4 that this bug was fixed https://euw.leagueoflegends.com/en/news/game-updates/patch/patch-94-notes
**"Neeko's W - Shapesplitter passive now properly damages turrets when Neeko has more ability power than attack damage"**
And i went test it in practice tool, and what i see: buy doran ring and passive W dont work, sell doran ring and buy long sword and passive work for towers.
Thats sad. Maybe it only for me? idk. If some1 can test it and reply in this thread i will appreciate.
