So I looked at your match history.
Master yi had Rageblade finished with 1/2 is jungle item and boots, an extra long sword, and a tiamat, by 15 minutes. He was over the top fed by the time the item was finished. The issue wasn't the item, since the math i ran in that one wasn't doing anything terrifying a BoRK wouldn't have done, it was all the kills he got by that point. That or he simply free farmed your jungle and your jungler didn't do anything to stop him. Either or.
As for the Jhin game, eh, it has a broken synergy with him, though he does take a damage nerf until he completes his essence reaver if he build's it before that one. It's not as much of a big deal as it migh appear. And his score line shows it. he was 12/8, not a bad KDA, but for the winning team adc, not a out of this world one. Im more impressed by the 4/0/15 tahm kench and the 10/5 Udyr to be honest, both who outperformed the jhin.
I feel like the issue is less the item and more your team lost the game across the map. Yi could have built anything and looked that good with so many early kills on your team. Jhin could of had a more standard build and done about the same, that was on your 2/7 teemo support for losing you that lane
(how does a teemo lose to a jhin? He has a blind that wastes Jhin's 4th shot! Freaking Teemo). I hope you have better luck than you did with your supports.
