Kha' Zix Jungle.

I suspect Kha'zix is the poster child for junglers that Riot wanted to tone down with the new jungle, make it more difficult for them to clear while maintaining health to gank.

That aside, I haven't seen a lot of Kha'zix in the new jungle.

I haven't really seen him in the new jungle. I played a match with some friends a few days ago and a buddy went Kha and got horrifically overfed, but then again the enemy team wasn't really warding and kept letting themselves get caught out. Hardly a standard match.

He has a really rough early game now, unfortunately, like I'm losing 40% of my health on the 2nd and 3nd spawn of raptor camp rough, but if you have high poke team comp he still does well enough, I just came off a Kha game where I got a quadra kill, but that was a normal game, I'd never try to use him in ranked right now. But as it stands, tanky fighters like Vi are the way to go right now in the jungle, with a few exceptions like Lee sin and Fiddlesticks, it's a real shame how restricted jungle got because of it's change.
