Katarina got too many nerfs

Hi summoners , i wanna say something rlly important , in last few months , I was really dissapointed about katarina , i am a katarina main and i have to say that she got just so many nerfs , everyone says she is op but now when i got a better rank is harder , and only because her kit is just so low , in lane phase is really hard and only because almost everyone know how to dodge her daggers, and even if you do a perfect combo and you hit both of the daggers passive you don t have enough dmg, she got so many nerfs , yes if you re gold you ll say she is god damn op because you don t know how she works but later you ll figure out and she will be useless , i have never lost vs a katarina because i know how she works , that s the problem , my winrate as katarina had a awful decrease after i got a better rank where players knows katarina . I am really sad because i don t wanna lose my main , please do something , decrease her dealy when she jumps on daggers , now she has 1.5 , maybe 1.0 sec would be better , or buff her passive so that if you hit the both daggers and R you can kill someone because she got too many nerfs , if i do a perfect combo in lane phase i can t kill the enemy while if zed does a perfect combo (hits the Qs) he kills anyone with no problem , or talon if she W and the enemy don t move , he can R Q auto and enemy is dead , so they don t have to do that much as kata . I don t think everyone will agree my opinion but i hope some people wilm understand me .
