While I don't agree with your post, I do agree with your title. I love Kat, ive been maining her since pre season 3, and I have to say that she is in need of a rework. The reason is not because she is op or anything like that, it's the fact that her kit does not allow Riot any wiggle room, meaning, nerfs to her kit either make the champion underpowered, or you buff her and it makes her overpowered. The problems with her kit is that you cant nerf one part without buffing the others. You cant buff her ult damage without increasing her basic abilities damage. You cant increase the animation time of her abilities without increasing her damage or giving her some cc. You cant nerf her damage without buffing her passive. Her kit just allows for no room for change whatsoever. I've never seen a champion like it. With the recent Kat qqing, and the fact that her and ban rate and win rate are high across all elos and regions, I think we will see one in the next two patches. The League community will not allow Katarina to stay as is, and I for one am up for a rework, because I want to play one of my favorite champions. I do hope they keep the reset part of her kit though, that's what makes kat kat.
