Wukong buffs?

No, and as someone who mained him in season 5 he frankly doesn't need them. This is the first time Wukong hasn't been straddling the fence or outright been overpowered top lane, but he's not bad. He's perfectly fine.

Let him be fine.

No.

I don't see buffs for the monkey from ages XD.

He's fine.

I personally thing they can put more utility in his W

During Stealth Wukong gains 50% bonus movement speed and if the clone hits enemies they are slowed by X %
