Neutral on this. While Kai'Sa does have all the things you said, she can fall behind quite easily, but camping a lane doesn't make the game fun for junglers, unless they only care about winning. She has good damage because of her base stats, that I can agree with being nerfed. Her scali} ng with AP is so strong, if you build
,
and
, she is capable of ulting in - after w which chunks you - and one shotting you with a evolved Q and using actives if needed.
I get that the plan for Kai'Sa was for her to be Adaptive to what the plays around, but players have already found the right builds for her, mostly revolving around Gunblade or Death's Dance. She needs to be put in some 50/50 state where we can truly just adapt to what we're playing against, which will make her feel strong as long as she builds the right items.
Once again, what do I know, I'm just a lowly noob.
