you're delusional.
I've been a Shaco main for the last 6 years and I have well over 500 games on him. I have a fair notion of what he can do.
Theres no reason for you to pick shaco in the jungle atm. He has 0 appealing things about him that are good for jungle play. They took away the blind which is a huge hit to survivability and beyond that he can only stack boxes on the first spawn. which makes 1st buff easy and you basically lose speed as the jungle catches up to your lvl 3 after clearing the other 2 camps you simply cannot clear.
He still finishes his clear quite healthy if you are playing him AD. The biggest difference now is that a Jungle item might need to be finished if you are not ahead enough to just rush an Ravenous Hydra.
The removal of the blind is not new at all, and has been in place for quite a while even before the rework. What he lost was the AS slow he had against jungle camps, but that was made up for by giving him a full crit on backstabs vs jg monsters, which is about 15% stronger than his old passive (assuming 1.0 AS and no CDR, becomes worse with higher values for AS, better with smaller ones).
The jungle is decided on how well you clear and IF YOU CAN CLEAR RAPTORS AND GOLEMS.
I know for a fact that I can finish my 3 first camps with basicly 100% health. If I'm ok with giving up about 10-20% of my hp, I can even finish those 3 camps with Smite still up. Red Buff is easy and Krugs are not a problem if your Smite is up. The only camp that you shouldn't go to without a Tiamat or enough levels is Raptors.
They gave shaco 4 abilities that scale off ap, if you're not using AP you might as well be playing ad heimerdinger.
He only has 1 AP ability more than pre-rework, while taking quite a hit to his AP cheeses with non-stacking boxes (not that they aren't usable, but cheesing a 4 box nest is almost impossible if the enemy doesn't dash to the middle of it).
Also, take a look at the items built and winrate for it: https://na.op.gg/champion/shaco/statistics/jungle
AP Items are on the lower end of winrates all the time.

He still is forced to Auto Attack to use his Passive, his Q, his E scales with AD as well, and his ult literally gives you a 50% damage steroid for your auto attacks AND procs your passive with a different timer.
I'm not sure where Shaco is a bad jungler or a bad AD champion right now. Specially since he's having a 4-5% higher winrate on the jungle than on Top lane.

POOR ME! I've always thought it was decided based on lane pressure and objective control!
