As a Yasuo main, I'd say patch 9.3 marksmen itemization pretty much nerfed him.
The real reason why any Yasuo player built PD was because it had the highest attack speed bonus amongst all Zeal items, which allowed him to get his Q to the fastest CD possible. The 12% reduced damage from the target he's fighting was just a bonus. That's not the case anymore, in fact it's become the lowest attack speed Zeal item alongside Rapid Firecannon. This limits Yasuo to having to build Statikk Shiv for the attack speed but inherently lose wave management because there's a high change that one E+Q will rid him of an entire wave to mobilize through which is why no one ever build Statikk Shiv on him anymore because reposition is much more valuable than wave clear. Wave clear is already done with his AoE from E+Q or Q alone.
Current Phantom Dancer also has a tacked on Lifeline ability that would hinder his build to go into a Sterak's Gage. An item that helps him survive in teamfights when he's in the middle of it all using his Ultimate.
Now to achieve more or less the same stats and build path that relies on a Lifeline item, he has to choose whether to go Statikk Shiv + Sterak's Gage and lose wave control, and ultimately losing his ability to run around through minion waves, or build Phantom Dancer and lose out early Q cd and Sterak's Gage Lifeline.
It's a 2 pronged nerf honestly. He builds Frozen Mallet still but again you'd still want Sterak's Gage along with the FM to allow Sterak's to proc properly.
