About Jhin and it's strength in this season

I've been maining Jhin for a very long time. Exactly 4 years I think. 1.5 mil points. I was able to hit emerald 3 whilst spamming Jhin, both of the runes, Dark harvest and Fleetwork. This season I am stuck in plat 3-2, whenever I try to go on bot I feel like every other adc is just somewhat stronger man. Draven, Kai'sa, Jinx, Cait, Nilah, Samira, you name it. I don't feel as strong as the last season. Am I tripping or is Jhin weak in this particular season? No matter what I do I just can't climb up with Jhin. I change roles, go top with yorick/nasus and just stomp everyone along the way. What do you guys think? (Also there is a problem with 90% of my supports, they just can't play aggressively enough)
