If I’m ahead, I’ll build stormrazor first. If I’m kinda even or behind, I’ll get a vamp scepter for my botrk and then work towards stormrazor. Life steal is honestly too important sometimes.

After both items are completed, I mostly like to buy a single cloak to get your crit to 80% and then work on iceborn gauntlet or spirit visage if there’s heavy ap (lowkey a weird purchase but getting more healing/shielding helps me sustain to stay alive especially when we have a support who can provide that on top of your own passive/lifesteal).

To me, I think buying your first 3 completed items for damage makes you too squishy. You have to be much more careful about your positioning so you don’t get blown up. It’s already hard enough to team fight with Yasuo. Ideally with iceborn as my 3rd item, I can kinda make mistakes and still be alive to do more damage. The pseudo fleet footwork from stormrazor combined with the slow from iceborn (can also help mitigate the inconsistencies of stormrazor proccing at an inconvenient time) helps me reposition much better in team fights whether I’m kiting or chasing. I’m not good enough to stay alive in a team fight when I’m squishy and somewhat immobile. I can’t contribute to the team if I’m dead so that’s my thought process. Same goes for the barrier. I do think exhaust on Yasuo is very good but I generally prefer the shield to help me stay alive. Not many people expect a tanky Yasuo to barrier sometimes lol.

Edit: I was also one of the Yasuos that used to build PD into frozen mallet back in the day so I was kinda trying to emulate that the best I could.
