Yasuo's {Passive} might be changed because everyone can have it, But Wukong's Stone skin won't?
For anyone who doesnt know what I'm talking about,
's Passive is called {Stone Skin} and it gives you 8 armor+MR for each nearby enemy at lvl 16 resulting in 40 additional Armor and MR lategame.
The design team created an item
that gives the same passive with the same name {Stone Skin} but gives you 40 Armor + MR with only 3 nearby enemies.
and now that the new
doubles your critical strike {Yasuo's Passive} , the design team is thinking of changing
's passive because of that, or at least it's one of the reasons.
You see, you have the ability to work on any champion and hot fix them in a day, but because Wukong is not popular at all , yeah, you still have no idea what to do with him.
Bonus: now Wukong's passive is even less existent because of the Last whisper changes.

has W, the ult heal and a tiny heal on her passive
has E and ult
has Q and damage reduction W
has W debuff and ult
he's more of a hybrid assassin than a skirmisher but has W and ult
situationally has passive and W
has passive and untargetable ult
this one isn't a melee carry but when in bruiser form some of his damage has vamp and has an untargetable ult
has vamp and the anti-CC ult, but isn't a melee carry either
this one is weird, but is still pretty much a drain-tank with respectable damage. He still has the vamp all over his kit and E
has a tiny passive heal but a powerful ult
is pretty much a tanky bruiser with a passive heal and W. This however is going too far because his passive sucks
Q has a heal, also W
small passive heal and W
passive, can gain a charge of passive with W
has Q and R steroid
has W heal and empowered W heal/cleanse

a lot of champs have passives that are really similar to items.
passive and manaflow band. ( yes I know they changed mb eventually, but it still counts
those last 3, are the next 3 while the first 2, have been mentioned by rioters to be in line with reworks
I doubt he'll keep his passive with the rework
