I really don't like stacking items on Yasuo. He's so squishy so you're banking on him outhealing whatever is attacking him. With Duelist I put tank items on Jax/Lee Sin (if I'm able to get one) and usually use Xin Zhao as a secondary carry unless I'm also going 4 Divine where I use a Warwick for that instead.
Xin Zhao, huh. I can't say I'm a fan of him. Always feels really anemic.
Here, I had the Duelist spat on Yone along with an Ionic Spark and a Quicksilver, then a Deathblade and Fist of Justice (or whatever it's called) on Yone. Shen got the tank items. Stuck a Thieves' Glove on Lee Sin, that actually put in some work.
My issue with trying to carry through Kalista here is that I only got the 2 Recurve Bows, and I needed one of them for the spat item, so there just weren't a lot of good items to stick on Kalista. Plus I was drowning in Long Swords.
(Truth be told I was going for the 3 Adept quest this go 'round, thus the focus on Yone. Just surprised it worked out this well.)
