#Remove her AoE heal
Now, before you get your pitchforks hear me out.
Fiora is the scourge of top lane, she's extremely oppressive and you feel like you can't really do anything against her. A trait she shares with other skirmishers like Tryndamere.
But unlike them she has a ton of team utility with that AoE heal of hers.
Honestly, if we were to balance around her being the "Grand duelist" I'd rather see her ult heal gone so she's at least an awful team fighter in exchange for the best 1v1 kit in the game.
Because I honestly feel there's not going to be an elegant solution to nerfing her.
