I played some Wukong today just to refresh my memory. He's not that amazing in lane because he runs out of mana quickly if you spam EQW trying to force damage. If you're against any of the popular manaless top laners you'll end up backing first that way. If you're against a squishy sure you can probably cheese them to death before you run out of mana, but the meta is tanky. Another issue with that is it's hard to rush assassin items because your lane opponent will probably force you to get defensive items unless they suck.
But he's alright because he can initiate teamfights better than any other bruiser, and arguably he can engage on targets more easily than other bruisers thanks to invis, but he's definitely held back by bad lane matchups imo.
