After Shunpo's nerf, katarina win ratio is now 48.91%
According to champion.gg Also, according to it, her win ratio is high if she wins before 20min. But after that , only late game she is a thing. 4% is considerably high. I suggest reverting her E nerf and nerfing her Q damage , but increase the mark damage. This way, kat would be forced to engage if she really wants to kill you, instead of making her have to spam Q a thousand times before she can go in for a kill. Right now, kat is unable to solo anyone mid except if you stay in lane way too much after she went b, or if you get ganked
