My love Wukong explained.
Way before the release the release of Duskblade & Stormrazor, my Wukong build was
(back when it gave both resistances)
The other item was either
or
or 
I love top lane and Wukong was one of very few meta top laners that could change a team fight in his favor by having survivability and using his ult. Whittling down the enemies and not able to be killed. If ignored, his ult would melt squishies, but shouldn't be focused because of how tanky he was.
There's literally no other AD champion I can think of that can jump in the middle if 5 enemies to engage while doing enough damage to multiple enemies to warrant retreat or focus.
The only relative alternate option to fulfill this role is
.
With that in mind, it should be noted that Wukong's passive and Jarvan's W both suck in terms of survivability, they need to be updated/buffed.

can do it with his ult if he comes from behind the enemy team without being noticed.
, he can get there but he can rarely finish.
, I never see them getting close to the marksmen/artmages in a team fight with anything short of flashing.
(Rhaast) is viable to fulfill this role.
, Wu and J4 can get the job done (there knockup plays a big role in it) which is why I think Aatrox/Kayn work.
