Jhin Changes
So several people think different things of Jhin. Some think he's completely broken and needs heavy nerfs. Some think he's extremely weak and needs some buffs. I think he is currently in a state of unbalance and needs both nerfs and buffs to make him viable. His Main Weaknesses These are the things Riot intended to balance him, but they might be going a bit too far.' Slow reload time: he spends 2.5 seconds reloading, with no way to lower that no matter what, after every fourth basic attack. And while yes, these four hits hurt, he has no damage while reloading, and a 2.5 second reload time is a huge window for people to capitalize on it and burst him down. And as he lacks mobility, it's not that hard for people to get onto him and kill him. As marksmen become more popular, so too do assassins because they can burst the squishy, immobile targets before they can really do anything. And all Jhin can do, especially while reloading, is bend over and hope they aren't too rough. Lacking mobility: again, in an assassin ruled meta, if he can't at the very least kite away from the assassins and outrange them, he's just going to be 1-shot. He can try to run away, but he doesn't have the speed to. Low ability damage: his Q does next to no damage unless you stack it up on minions first, his W literally only exists to snare people and maybe try to long range snipe when your ult is down, his E is extremely unreliable damage, and his ultimate deals a lot but is extremely difficult to hit unless your team has full control of the fight. Crit damage is lowered by 25% overall: not that huge of a deal, except that Infinity Edge is putting you up to 187.5% damage on crits rather than 225%. It makes the item, though good because you want to get a 100% crit chance build, just poor and often makes it get switched out for a cheaper item that'll actually help him more. How I would fix these problems: Reload time: make his reload time lower based on level, down to maybe 1.5 seconds. Lack of Mobility: increase the movement speed he gets from crits and increase the attack speed to movement speed conversion. Low ability damage: buff Q, W, and E base damages and maybe make E a little easier to hit (maybe when you kill someone the trap that spawns and detonates on their death location has a lower timer?). Make it so that his normal crits deal 175% damage flat, increased to 225% with IE, and make it so his big crit still deals 25% reduced damage from a normal crit (so it would still deal 187.5% damage with IE).
However, these buffs can't come without nerfs, or else Jhin will become dominant and destructive. Jhin's Main Strengths The things Riot intended to be what makes him good and worth playing, but when you get ahead they just go out of control and make him seem legitimately overpowered. High attack speed and crit chance to AD conversion ratio: just like it says, he gets too much AD from crit chance and attack speed. I've gotten over 1000 AD on him, and it's not even that hard. Jhin is a snowball, and once it gets rolling, it doesn't slow down. However, if he never gets rolling, he might as well AFK because he doesn't do enough of anything to be relevant. High E scaling: while yes, his E is extremely unreliable to hit, if it does hit it's not going to feel good. I've had a Jhin Blitz lane before where I just pile a ton of traps in a single spot in a bush, Blitz pulls the enemy onto the traps, and just keeps them there long enough for the traps to explode and take them from around 70-80% hp to 0. Yes, his E is unreliable, but it does way too much damage if it can get it off. How I would fix these problems: simply lower the crit chance and attack speed to AD conversion and lower his E damage.
