Is Kha'zix Idiot proof?

its not about if he is idiot proof. its about the idiots against him who isolate themselves when they are running away.

Not really.

Better to look up his builds and pathing. He is top tier as a jungler, but if you don't know how to play or jungle, you are going to hurt your team.

he is easy. But some tricks are huge for outplaying and doing a ton more damage. The e root thing, managing the passive, ult to deny autos or some big stuff ( ult)

Atm he is because hes so overpowered and his play pattern is basically : jump in range > mash Q until your target dies.

Kha'Zix is far from idiot proof, he's just strong.

If you don't use his isolation and short stealth windows properly then you'll get nowhere with him.
