Not saying that melee carries like Tryndamere and Yasuo should be ignored by Riot, but since this Static Shiv change, on Tryndamere, you should get a Tiamat early on for the wave control like a lot of Tryndamere mains have been doing for awhile. Tiamat does have the advantage of you still being able to somewhat freeze waves if you want to or shove the wave, compared to Static Shiv, where you have to shove the wave whenever the proc is up and you want to last-hit one minion. You can still get the Shiv later for additional clear and AS/crit, but the Tiamat early helps Tryndamere a lot.
This obviously doesn't help Yasuo at all. Tiamat is not a great buy on him at any point in the game, probably mediocre to subpar at best, and there hasn't been a recent time where Shiv has been preferable on him. He's been pigeonholed into Phantom Dancer because the passive on it is far too strong for him not to take it. Yasuo honestly needs a light rework because he's either God-tier or dumpster trash based on even seemingly small rune/item changes.
