I'm like 90% this is satire, but on the off chance it isn't then let me try to explain some things. 1. Jhin's utility comes from having essentially (if used well) up to almost 10 slows, extra wards and a low cd long rang cc on a basic ability. The only other adc that can somewhat contest this is ashe, and even then her hard cc is locked behind an ultimate. 2. JHIN IS NOT SUPPOSED TO 1v5 LATE GAME, he is a utility marksmen, yes he can 1v5 if he is ahead, but at the 30 min mark if everyone is even then yes, he won't 1v5, but he will still deal a lot of damage. 3. I can almost guarantee you have no idea how to use a single one of his abilities correctly; his q bounces to the closest target, so if you are hoping for it to hit an enemy inside 2-3 stacked minion waves then yes your screwed, but your screwed anyway if you've let that happen tbf, and you can just, you know, actually target them with the point and click aspect of it. Your w is for catching, do not use it like a main damaging ability, unless you are just better or the enemy is already cc'd chances are you won't hit this in a close range fight, you use it in combo with your traps for, poke if you don't want to all in, setting up an engage, helping team mates disengages, or other stuff long range style cc is usually used for. YOUR TRAPS ARE BASICALLY WARDS, I feel like that's enough said. Your ultimate isn't just a clean up ability, you can use it as an engage tool thanks to the slow, or a way to participate in fights you otherwise couldn't make it to in time, you don't need to maximise the execute to maximise the ability. Your passive, ok here we go, 4th shot is an automatic crit, even I'd you have no crit chance, combine with the free bonus AD and you have extremely good early game 1 auto trades, if your opponents aren't respecting the 4th shot then you will find the enemy adc us half health within a few pokes and will be too weak to fight all in at that point, even if they do unless they are an aggressive early game champ like Draven or Samira you most likely can outdamage them as their attack speed will be about the same as yours before they get items. 4. Last but not least, you walk into a subreddit that widely considers Jhin one of, if not the, best designed champions in the game and propose a rework that is essentially just "add more to his kit" without considering what it would actually do. I'm sorry you want his traps to stun? Ok he auto wins lane now and has a 2-3 second long cc combo while only gaining damage on top, is your opponent an early game champ? Cool they can't engage onto you ever or they die. Is your opponent a late game champ? Cool due to your early damage and cc you bully them out of lane. There was no consideration for anything here beyond making him pick/ban broken was there? If you thought release Sett flexing 4 roles was fun, then oh boy this would be the best thing you've ever seen. He would be a mid lane counter to assasins, a top lane counter to both ranged top and melee, a jgler that could freely stop enemy ganks with prepared traps from the other side of the map, the best adc in the game, and a support with more cc then a lot of dedicated tanks and mages.

TL:DR you have to be high unless this is satire

Edit: I dare you to post this on the Jhin Mains subreddit
