An idea that might fix up Ahri's current situation

So I've been seeing a lot of people saying that the Ahri nerfs are going to far and I agree, but she definitely still needs some toning down from what shes like right now. And the way to do that I think would be move her speed boost from her Q to her W and lower the amount of speed it gives, but to compensate for the lowering of the speed make it so it doesn't run out until all of her fox fires are gone that way it can still be used to position yourself before a fight breaks out and it can kind of still be used as an escape move. You could almost think about it like Teemo's speed boost because then her W could be used to get back to lane faster, roam, or just be used as a quick boost for an escape. I believe it would give her W a much more strategic use and would not be to overpowered because it won't give as much of a speed boost and can be easily interrupted by getting close enough to her.
