It's old Wukong who traded raw burst for a better engage distance. His new W is better as a dash than it is for deceiving the enemy, and gives him insane target access.
Now that the E does magic damage and the Q damage got nerfed, full lethality Wukong will deal less damage. However, raw AD Wukong can just fly in and one-shot somebody before stunning the entire enemy team as he retreats. He's gonna be cancer until they gut him and then he'll be useless again.
Do they really think that a physical damage shield that scales with health is going to encourage Wukong to build health? It won't. It will be a decent passive for trades in the early game that will quickly become nearly worthless in teamfights when the only way for him to lose vision is with his E and his enemies start slinging multiple damage types at him.
I hate how they're just changing everybody into assassins. They did it to Aurelion Sol, and they're doing it to Sylas, too. Instead of addressing the burst meta, they're just making everybody into burst champions That's the only way damage gets dealt in this game, sustained damage is worthless with all the lifesteal and spell vamp people can access.
What we need is for damage overall to go down, so only a hyper-fed assassin/burst mage can truly 100-0 somebody. The role of an assassin/burst mage should be to 70-0 somebody or 100-30 somebody, either taking down a soft target or bursting down an enemy for their teammates to finish up. Create better bruiser itemization, especially for AP bruisers, so that they can actually be bruisers and not just assassins-with-slightly-more-HP. Suddenly, tanks, enchanter supports, and ADCs can be relevant again. Mages could go midlane instead of support because they can actually step out from under their tower.
The devs know that the teamfights are the fun part of the game, the parts that people enjoy the most, both to play and to watch. Why do they keep trying to make them shorter?
