OK, so after playing some Wukong, I've reached a conclusion: it's all on his W. To succeed at him you absolutely, POSITIVELY have to W at the right times, because it amplifies your tanking capabilities so much it might as well be Alistar's R you got there. I get the feeling his best build, when played perfectly, is super glassy pure AD with maybe a banshee's to block CC, but I'm afraid to try it out until I get really good at cloaking at the right times. I get the feeling this makes Wukong basically impossible to use in a high-tier game, but if Westrice can make Akali work Wukong is probably viable. Regardless, other things I noticed:
-He loves CDR. With two low-CD boosts at his disposal, particularly the Q that can be abused to keep a target PERMANENTLY debuffed of 30% of his armor, it makes him super scary and gives him some big damage.
-If you're building mana on him you're doing it wrong. You have to be spamming every single skill just as they go off-CD for two straight minutes to oom on Wukong, so manamune, while it looks tempting, is actually a super terrible buy. Sheen is probably also terrible in spite of his high base AD and the fact that he benefits from every Triforce bit - just way too much money spent on stuff that doesn't make Cyclone rock, and everything it does Ghostblade does better (speed? Yep. Chasing? Yep. Roids? Yep. Extra damage? Not quite, but close through ArPen).
-Speaking of which, Cyclone is your main damage. The rest is pretty much just atrezzo, really, the bigger brother of Judgement is what gets kills because at max level it's like tacking two bloodthirsters to your basic attacks and getting one free knockup per enemy. I'm undecided on whether it's best to just trust the bonus damage or complement it with some AD, but it really feels like 200 AD is the magic number before stacking more becomes questionable - at that point, you're pumping out a meaty 1.6k damage pre-mitigation, which is more or less a squishy's total base HP. Once the bug on shreds gets fixed, a combo of Q + brut + cyclone should hit the carry for basically true damage.
-Atma's feels "luxury core" on him. Wukong doesn't need THAT many resists, but a little defense goes a long way and Atma's ensures you can get some beef in case your W doesn't work out while still gaining damage. It also combines wonderfully with ghostblade to get you close to the magic number and give you a ton of extra damage through crits. I probably wouldn't build it as my first core item, but once I pin his core down, I know for sure what I'm rushing next unless the enemy team is all magic.
I'm still fumbling around looking for his core though - any ideas on what the best item to rush on him would be? Brut seems tempting, but I feel like it doesn't provide enough bang for the buck as the first item. Maybe it's just that it's not that flashy but remains a great choice, though.
