Why does Katarina needs no effort as a Assasine?

is currently at the highest winrate of all champion, which is very strange since assasines are usually harder to play and need some effort to actually win the game. Not every player is good, so assasines usually get below 50% winrate. So how does Katarina got to 55%?

Lets compare her with some other assasines. has a skillshot, energy use and is kinda weak if he got no ult. needs to hit her chain to actually kill someone + she burns her escape for dmg. is mostlikely dead after using his ult for dmg, since he has no way to escape ( if we can still call her an assasine) relies on her mana and has 2 skillshots. 1 of it is also her main dmg tool. , same as Talon, has no escape once she jumped into the fight.

has no skillshots, no mana and can still escape after she pentaraped your entire team. There is actually no effort you have to put in her. She has a safefarmingskill, a 10sec flash aswell as resets. The only real effort you have to make is waiting 4 sec before jumping in the enemy team and powerfist qwer.

I played Katarina alot, and i have to say that i really get bored to get 22/0 everygame without actually doing anything. Her effort-:rewarding is just way to unbalanced resulting into a 55% winrate.

And if people are still saying "Muh, just cc", then good luck ccing her if she kills you within 1sec.
