Ahri hasn't still received a notable nerf
Why hasn't she received a good nerf? The last nerf she received to her sustain was pretty minimal compared to everything else she has on her kit. Her Q makes her ungankable and gives decent damage, her W adds to her burst, E is basically a death sentence unless you're a tank and her ult makes her either ungankable or undodgable on teamfights. On top of all her mobility and damage, she gets the sustain from her passive and also can either roam or lane very effectively, and she has barely any hard matchup
