Typically, I just lock in Berserker's Greaves into Shieldbow into IE first. If I'm behind or need anti-heal, I grab Mortal Reminder second or third, no question.
But the rest of the build is such a headache. After the Bruiser item overhaul, everything's just loaded with Ability Haste, so it feels like a massive gold sink. Say I don't need anti-heal right away and go for Death's Dance third — building a Caulfield's Warhammer feels like throwing gold away. Caulfield's itself isn't exactly gold-efficient, and then they slapped Ability Haste on top, a stat Yasuo doesn't even need lol.
If I try going ADC items instead, nothing except Bloodthirster offers any defensive stats, which means I'm just walking in, drawing aggro, getting focused, and getting sent straight to the scoreboard. And Bloodthirster, even with the lifesteal helping me survive, deals no damage for its cost.
So my last option is tank items, but those are also spammed with Ability Haste. The few that are worth the gold are Randuin's Omen, Frozen Heart, and Force of Nature. But Randuin's and Force of Nature are wasted on Yasuo since he's already naturally mobile, and Frozen Heart is such a garbage item that even tanks skip it unless they're Rammus.
After trimming it down, all that's left is Death's Dance, Wit's End, or Guardian Angel. None of them have HP, so you're basically made of slightly tougher paper. Man, I miss you, Frozen Mallet — giving AD and HP while helping with kiting...
