Mundo Jungle sleeper OP?

Been playing some mundo jungle games as of late, and it's gotten me out of my losing streak pretty easily (from S5 now almost to S2 promos).

He's pretty strong and can clear waves super fast, makes great use of the (nerfed-then-buffed-again) cinderhulk; and he can duel a lot of other strong junglers (or at least stay on par/pace with them).

I've been maxing E > W > Q in that order, and taking either exhaust or ignite (depending on enemy comp), since mundo is a big tank and if you're caught out that badly, I don't see the need for flash -- you're usually going to be peeling for carries and be all up in the enemy team's face anyways.

Also I've been just starting wraith camps with W first, then leveling E at lvl 2 and usually am able to steal blue buff (if on red side) OR start the enemy's wraith camps and steal red buff (if on blue side). Pretty OP -- just cleared out half of a lee sin's jg and also a kha's jungle easily.

Any other Mundo junglers out there feel this is his time to shine?
