If I could change one thing about katarina
I would make her ults damage ramp up over time instead of flat intervals.
E.G. instead of 25% ap every .25 seconds for 2.5 seconds, it should start at 10% ap than halfway through the channel it deals 25% ap per hit, with the very last hit dealing up to 40% ap, with the total damage remaining the same
everyone should know why this would be a healthy change but ill say it anyway.
it would make kat more skill based and less ez pz pub sleazy.
it would also give players a fair chance to react to her ult, like the recent change to rivens ult, instead of instadeath.
