Wukong was my first jungler, and although he is not played so much,i love him as a champion and he can just turn around a game by himself.

Pros:
Attack speed from E helps you clear jungle camps more easily
If you position yourself good you can knock up the entire enemy team which combos EXTREMELY good with a Yasuo
E,Q combo deals insane damage after you get Triforce
Can juke great with clone

Cons:
If you get invaded and you miss the blue buff you will have hard time in the jungle as you are pretty mana hungry
W doesn't help so much in the jungle, only at ganks
If you get knocked back while Cycloning you will just have used your ult with no reason

When fed enough,you can just lead in the teamfight by using E,R and then letting your team initiate. However you should not try and dive everyone in the turret because you are "fed".

When jungling you will probably want to start with your E because it will grant you attack speed to clear the camp more easily.Anyway lead in with your Q to reduce the monster's armor and then use W if you are receiving too much damage.Then use your E again and finish of the camp.
