Can we rework Kai'Sa please?

Basis: She's overpowered and her kit is overloaded. She has THREE Passive abilities. She has evolving skills that require only stat growth, essentially giving her rewards just for playing the game. Her ultimate is a blink with a shield that scales off her damage stats.

What the hell, Riot? I've seen this champion absolutely destroy in matches for no reason whatsoever, I've ganked her at level 2 and nearly had my whole HP bar evaporated (No I am not exaggerating), and toward the end game she's impossible to kill thanks to her stealth and shield giving her an out while her team protects her.

Not to call out the dev who designed her, but seeing as how he's responsible also for the Rift Herald it's not surprising to see something this busted coming from the same guy...

Maybe I'm just 'old fashioned' since back when I played regularly champions that had 7 abilities had them mapped to 3 buttons and a single ultimate, and didn't really have a passive to accompany it. Now it seems like every new champion does like 15 things on 4 buttons with no reason behind it. Sylas is another good example of "I DO ALL THE THINGS!" for no reason. Kingslayer! It does damage! I heals! It executes! You can spam it! Abscond is a gap closer with a shield! Oh wait, it also is a second gapcloser with a knockup stun! [zombie-brand-mindblown]

I'm sort of ranting here but I'll summarize: Cut back on her kit, it's way too powerful. Or just give me like 15 bans so I can make my ranked matches not a dumpster fire of cancerous champions who never get balanced. So far my permaban list is Fizz, Kai, Galio, Trynd, Neeko, Pyke, Irelia, and Yasuo. These champs are all cancerous and not fun to play against cause most of them are mains who need to pick someone that isn't faceroll and learn to play something else.
