Chogath. No escape, but when you're that tanky screw escaping.

Vi is an amazing jungler. I ALWAYS jungled lee sin, but I just bought Vi and have been loving jungling with her.
Edit: Forgot to mention the reason I like Vi more than lee sin atm is that she doesn't fall off late game whereas lee sin does.

Nocturne makes things happen, and was made for the jungle.

If you want someone with more cc and tankiness, try Nautilus.

I say lee sin I've seen lots of people use him for jingling pus he's a great damage dealer and quick in and out of battle

If your willing to put in some effort to get used to them then I suggest Shaco, great ganks, very hard to catch and trollier than trundle, that being said he can be tricky to learn

No love for Udyr? That 5 second stun at max level is pretty damn good if you ask me.

Plus his early game clear time's are insane and by the late game with some tankiness, you don't die and can do some fair damage with a Witt's End and Tiger Form.
