Kai'sa needs a slight nerf.
She has a Attack Speed Buff on E that also makes her invisible for building items. Her Q is like Ahri W, absolutely braindead. It says "Hey, are you in this range? 200 dmg". Her W is a Jhin W without the slow that allows her to use her ult. Her R is FUCKING BROKEN on an Adc. Who the fuck needs a support when you have a 1000-2000 health shield for some-odd seconds. She 100% of the time builds Guinsinoos because it applies the bullshit passive of hers twice AND it allows her to activate it stupidly fast.
