Kennens base damage needs a nerf.
I like what you guys did to fizz. You nerfed his base damage while buffing his ap scaling. That made it so that people could not build tank fizz anymore, but there are still some stubborn players out there.
Anyway I hate facing ad kennen who does so much dmg early on. Makes it really hard to farm, so I think you should decrease his base damage while increasing his ap scaling just like you did on fizz. I've also seen a lot more of ad kennens running around lately.
