Stop building Wukong Tank
Let us be clear THIS GUY
is not a tank, stop building him like one.
Obviously I main Wukong. Wukong is not a tank, he is a damage dealer. Stop building him with 3 tank items or even full tank, its horrible. I Personally play wukong as a midlane assasisn, never top / jungle bruiser for the following reasons.
1. The AD scaling on his ult is insane
Even without your Q + E, your ult has insane scaling at all stages in the game, you can literally 100-0 entire teams with a well placed and timed Wukong ult. Use your W from the fog of war to engage, flash if you need to. E + Q who you want to die first, then watch was your primary target is deleted instantly, and the rest of their team is at 30% wondering wtf just happened and why you do so much damage.
2. Tank Wukong does nothing after his ult is done
Just a fact. After your ult is done the only thing you can really offer your team is an armor reduction on your Q, no more CC or even slows, you are essentially a tank
at this point.
3. Wukong's passive combined with offensive item auras and dangerous game is more than though to keep him alive
The above is pretty self explanatory.
MY WUKONG BUILDS
Standard
Brutalizer ----> Hydra -----> Mercs -----> LW -----> Cleaver -----> BT
Sell brutalizer lategame for anything you need
VS AP Heavy
maw ---> Hydra -----> Mercs -----> LW -----> Cleaver -----> Murcurial Scepter
Upgrade hex to maw late game
VS AD Heavy
I somtimes substite BT for 
's ult is insane too, and is instant. Yet do you see anyone building him full AP? (Not that it can't work, but Tank Malphite is much more effective).
I'm sure this would be fairly decent. He can also setup nice
ults for instance
