It's Most Likely Been Said Already Butttt....
Made a new account, SUCC Ghast back in 2016, started playing it again. I am maining adc on it, and if you look at the account I have good and bad games, but those games were mainly my fault if I performed badly or not. Now you will see a lot of Jhin gameplay, and god damn is he a fun champion even if you happen to be really bad at him. But Yesterday... oh Yesterday, I am gonna be having some flashbacks. New adc items don't work with him, at least not early or mid game. All crit+damage items have been removed, items that give base crit to increase Jhins passive AD. So, this leaves him in a bad spot, you could rush the storm sword bullshit, but overall it doesn't compare to the old infinity Edge or Essence because it doesn't give him what he needs. His scaling is low because of his passive, and he cant even take advantage of it until mid to late game, if he can stay on par with the other adcs.
Basically, I would like to suggest that Stormsword thing's crit damage it gives, and the auto crit, somehow apply the bonus AD to Jhin when he fires the shot, this way he doesn't lose out on what made him viable. 600 Gold Brawlers Glove is also ridiculous, and I know I am complaining but honestly, try playing Jhin, you rush Firecannon and you get outscaled, you rush Sword thing and you get outscaled. Bummer dudes, am I just playing him wrong now or does anybody agree with me?
