I've been seeing these same board about wukong being weak.
But is he actually weak?
1st of all he is AD, he can abuse AD assassins item or bruisers item with that Trinity force + Sterak gage.
He snowball relatively easely since his laning phase is him spamming his E for harrass.
He synergize super well with Black cleaver since he can shred an entire team armor.
So whats the problem? He isn't suppose to 1shot because he is a Diver not an Assassin, even when he is ahead he can 1shot champions.
That 0.56% playrate means that there are good wukong mains. It's just that the wukong players aren't good at him.
