best off meta jungler

Skarner with Runeglaive is not expected and yet it works wonders

the muhfuckin Godyr

Great performance in the jungle with great clear, great mobility, great ganking, great stats and is godlike with sated devourer. He can stay in the jungle for forever thanks to his sustain and is the best champion in the game for catching people out of position.

Skarner, Nocturne, and Udyr are all....meta.

I think by non-meta he means champs who can jungle surprisingly well if you're already great with the champ but make your team rage at you. Like...

Best non-meta jungler is Poopy. Her lategame is as bananas as ever and hanging out in the jungle leads to a relatively safer early game. Her ganks aren't even that bad if your laner has hard CC or you can flank and tackle the enemy into your teammates or a wall. Her burst damage is good at securing kills and once she has a sheen she can usually defend herself vs invades pretty well. (Jungle is full of narrow areas that make smacking people into walls easy.) Her early clear is garbage, but lane poppy struggles early too and farms poorly so it's not that crippling. Try it sometime.
