Fiora has a 42.3% win rate in Diamond SoloQ right now. She was really overnerfed in 6.6
She was nerfed because of the tanky build but in the exact same patch Riot also nerfed Titanic Hydra, lowering it's AD by 15. But that isn't the real issue, the real issue was the reduction of her E's slow, lowering it to 30% and making it no longer scale. This is devastating, it was already really difficult to hit all 4 ult vitals and after that change it's even harder, not to mention that you can buy QSS or hug a wall to completely negate the ability anyway. Of course, she's a very difficult champion and should have a slightly negative win rate, but both Azir and Ryze are at around 48% win rates.
Will Riot consider reverting her nerfs?
