Is Tri Force Yasuo Dead? ( Patch 6.11 )

I agree. Doesn't seem very good on him anymore

Maybe Shiv + IE + Tri?

Does it matter? Doesn't he have other options that give him Crit and Attack speed, on hit effects, without the unused mana portion?

Yasuo will probably resort to a different build. Honestly though that TF & PD build alone didn't offer the best stats for a bruiser. I would personally prefer PD and lifesteal.

he might still build it. at least i think so. probably later on than he does now, thougth.

You could opt to build it as a 3rd item after PD/Shiv + IE but it doesn't really seem worth it anymore

I don't think this build path will die out. Trin provides a lot of stats that benefit Yasuo, and crit chance wasn't the core component of that Item. It was just one of the great bonuses that was very welcome. Phage is extremely important for his survivability against hard match ups, and there aren't any items that are good on him that should be rushed that early into the game. My way to go will be (tested on PBE) PD into Trin, after that I get crit cloak that I'd leave there chilling, and revisit it once I've bought lifesteal item and Visage/other defensive item. Yes, I'd leave IE as last item.
