If this isnt proof, I dont know what is

needs a full overhaul

It's pretty apparent that after being nerfed over and over and over and over and still remaining a top tier jungler that their is something intrinsically wrong with his kit that numbers adjustments alone arent solving. Pick your poison but he's still at a 53% win rate. This guy has been nerfed like 5 times this season alone and he's still near the top.

"But he was forced into a bruiser build"

NOPE. That's not true at all. Nice try.

First off, you need to undo those buffs on the PBE. He does not need any buffs at all period. His AD assassin build is just fine. I don't want another patch of completely broken Shaco AGAIN when those changes hit live

You need to do something about his Q. 4.5 seconds of uncounterable invisibility attached to a flash is bullshit. You removed the counterplay to this ability in the preseason when you changed it from stealth to invisibility. I cant understand why you did this.

You need to do something about his clone damage. This is probably the biggest reason he stays near the top because its never addressed. it does 75% of his damage and has I-frames attached to it.

Some major mechanic of his kit needs to be changed. Its pretty damn obvious that numbers nerfs barely touch him
