If you make an AD version of Zhonya's Wukong's win-rate will GREATLY increase because he can full channel his 4.8 total AD ratio ultimate without being displaced/damaged and the ultimate currently does not get cancelled with the use of live-Zhonyas. The only reason it is NOT built is because Wukong does not realistically scale off of AP. And the item doesn't give AD.
