It's pretty obvious NOBODY likes Katarina
Low pick rate, low win rate, completely toxic and garbage to play against at all stages of the game, and can go from 0-8 to 5-8 in a single misplay in a teamfight. It's time to remake her entirely, and rebuild her without her resets. It really isn't even an option at this point.
Who cares that you can "Save CC for her". That's literally the way to counter every single champion in the game. The only difference is, if you don't have CC, you instantly die with no counterplay.
