Yasuo after ADC item update

Trynde builds ER because he needs another crit item to reach 100% crit chance, and another Zeal item would be too much of a waste (his worst winrate is with both PD and SS). It also granted him 30% CDR when he bought it, which is huge value as a second/third item, but now with only 20% CDR, no crit chance, and passive that doesn't work that well with his ultimate, which works best with engage ultimates such as Kai'Sa or Lucian. Yasuo building any CDR is laughable, his Q and E are already on incredibly short, static cooldowns.

Trinity on Yasuo, however, is a different situation. It used to give critical strike chance, which worked great with his passive, and the on-hit effect popped on every single one of his Q's. That's an extra +200% base AD per Q, which is still a huge buff, and champs still take that on Yas today, even in diamond. It also grants health, very valuable to Yasuo, who needs the extra tank, and it has another passive that helps with his positioning by giving him an extra 20 or so movement speed per auto/Q. The extra CDR on this item is really just a bonus, and the existence of mana on it makes it a 100% luxury item to only buy if you're already ahead.

He'll still have it (unless it doesn't multiply with his passive, and instead adds, in which case, rip Yasuo), but his passive reduces his crit damage automatically.
