I've seen jungle Mundo a lot lately, and I usually see him lose. I don't feel that his ganks are strong enough, and his counter jungling doesn't seem strong either. Am I overlooking something?
Dr Mundo is a great jungler. Saintvicious from Professional team Counterlogic Gaming uses him often. He has really fast clears which allows him to counter jungle.
His ultimate and his Masochism(
E) allows him to be really strong and really hard to take down allowing him to be very good at resisting counter jungling.
His ganks do rely on his clever so I run him with exhaust and smite to help with his ganks.
Another thing that makes him strong is that he is stronger than other junglers late game.
Mundo has a very strong counter jungle. With burning agony you can clear waves very fast.
He also does more damage the lower hp which helps his clear times.
His cleaver also does a lot of damage to dragon and baron.
On top of that he can absorb a lot of damage late game which can be useful during team fights.
