It's not fucking working. None of the runes feel good on him, I've tried everything from comet all the way up to predator just to see if he has synergy with anything. Without DFT he feels so lackluster when everyone outpaces him bot.
Now that's not to say he's not good, because well, He is good. Just everyone right now is better because of their synergy with the new rune system.
I mean, am I missing something? Just go comet and hope for the best?
GankedByWindows1 votesPretty much. None of the runes have great synergy with him.
-Fleet Footwork would be nice, but the 20% attack speed isn't great on Jhin. Maybe with the buff next patch it could work.
-Aery is okay if all you care about is lane pressure. It doesn't scale too well
-Comet scales pretty nice and can be guaranteed if you land a root, but its hard to do consistently. It does work with your ult as well.
-Electrocute isn't bad, but it does force long extended trades for you to get it off. In some lanes you just can't do that
-Trust me that Dark Harvest is bad. It just doesn't ramp up in time.
HarrowR1 votesAery is very good on him,so many times ive killed someone cause of the aery extra damage,dark harvest can also be good on him if he gets ahead,his huge damage plus duskblade proc plus dh proc is easily over half of squishy hp in one shot,try it
Therion771 votesOver 600 games played with Jhin, and I can say that I am completely unhappy with the new rune system when it comes to him. I played around with Grasp of the Undying a bit. If you're more than decent with your poke, even though it's reduced HP gain for ranged champs, you can squeeze an extra 150-200HP out of him during the laning phase. If you go Overgrowth you should be able to squeeze an extra 500HP out of him by 30 minutes. If you get really bored, buy Warmog's as a 3rd item (after boots) to really confuse that Zed midlaner, and watch him scratch his head when he dives and ults you, and you don't instantly fall over. If your team is ahead you can go Bruiser Jhin and scrape an easy 3200 - 3300 HP with frozen mallet. It's kind of funny.

Might give this a shot.
ZURELL1 votesrun and shoot. somethings bound to happen 8)
Kythers1 votesfleet footwork with flat ad would be ideal on him, but the rune system is silly
LethalTempo Jhin1 votesNone of the keystones really work with Jhin...
Right now Comet is propably the best because of its scaling, but can be hard to land with Jhin (W and R). Aery is an option if you want to poke a lot (with supports like MF, Xerath, Karma). Electrocute is viable with all in supports (especially if you duo with one).
Don't bother with Dark Harvest, it just sucks. Takes way too long to get going.
Fleet is propably still not going to be good into huge majority of the matchup, even after the buffs.
As of right now, the only reason Jhin is looking strong is because botlane pokewars are back. All the high elo top tier ADCs (Ezreal, Ashe, Varus, Jhin, MF) have obscene poke. 
is the most popular right now from what I saw in challenger/Kespa cup.
Even though the 
or are still good.
When lethality inevitably gets nerfed in future (i am certain that it's going to happen sooner or later), Jhin is going to struggle again and fall in winrate.
Therion771 votesThe Lethality Jhin builds are for people that can effectively dodge skill shots and actually have a team that knows how to protect the carry, and Youmuu's is questionable in Bronze / Silver. Down here in the dumps I've always found it better to go max damage and pop squishy targets, even if it means sacrificing myself sometimes. Lethality, as broken as it is, is still pretty worthless if the other champ has no armor.
The only time I buy Youmuu's anymore is when I need to push a lane early game and need the extra mobility, or when that enemy Nasus top lane is 5 / 0 ten minutes into the game. It probably makes total sense in the higher elos, but not down here in Bronze and Silverville. Sometimes those pro-builds just don't fit the playstyle in my elo.
LethalTempo Jhin1 votesWait what?
You don't build lethality against tanks. You build lethality to pop squishies.
Lethality is flat armor pen.
If you have 40 lethality and attack a Varus, he is going to pop.
If you have 40 lethality and attack a Maokai, he is going to laugh in your face.
Against tanks as Jhin, you build this 
Against squishes as Jhin, you build some of this 
Therion771 votesSince the new rune system there are no more +Armor runes (unless they go Resolve, which is rare in bot lane.) It made perfect sense before the new patch since 1x Lethality item (Youmuu's or Duskblade) would completely negate the bonuses of the runes. Now it doesn't because the enemy ADC isn't going to have any starting magic resist or armor from their rune pages. There are a few champs that get passive bonuses, sure, but down in bot lane, what's the point? --- Please, try to convince me. I may be mistaken, but I don't see what good lethality is going to do on squishy targets that critical strike and the passive from Infinity Edge wouldn't do better, even if it is halved on Jhin.
It still makes sense to build Youmuu's if the enemy ADC has Ninja Tabi, because it's a cheap counter, but outside of that... Eh? You tell me.
Flat Armor Penetration = Lethality × (0.6 + 0.4 × level ÷ 18)
The formula won't make it as if the target has negative armor. If they have 0 armor to begin with, lethality is useless and grants no bonus.
LethalTempo Jhin1 votesLethality scales with your own level.
This is going to be a math class to help you understand how lethality works.
If you have 40 Lethality (which are 2 completed 
items -> 2 of ), then you reduce target's armor by:
Flat Armor Penetration = LETHALITY × (0.6 + 0.4 × level ÷ 18) -> Your armor penetration is always at least 60% lethality, the remaining 40% scale with your own level (which is y2,2%, where y = your level)
Example: If you are level 9 and have 40 lethality:
Flat Armor Penetration at level 9 = 0,640 (you always have 60% lethality effective at least) + 0,240 -> 0,840 = 32
-> At level 9 you have 30 effective lethality.
Now into the in-game example.
If you are level 9 and have 40 lethality and there are 2 champions, one of them is a 
(who built 
, and has a 
), the other is a 
(who has no armor item).
at level 9 has 66 base armor. His Sunfire Cape, Ninja Tabi and Frozen Heart give him 190 armor, so he has 256 armor. To keep it simple, I am going to assume Maokai doesn't have Iron Skin (+ 5 armor rune) or Conditioning (+8 armor after 10 minutes)
If you (level 9 
) attack a level 9 Maokai with 256 armor, your 30 flat armor penetration (from the math above) reduces Maokai's armor by 30 -> Maokai has 226 effective armor against your physical damage dealing attacks (Jhin's autoattacks, Q, W and R), which is a 69% damage reduction against your physical damage (as opposed to 72% if you had 0 lethality).
(sidenote: damage reduction = armor / (armor + 100))
at level 9 has 55 base armor.
If you (level 9 ) attack a level 9 Varus with 55 armor, your 30 flat armor penetration reduces Varus's armor by 30 -> Varus has 25 effective armor against your physical damage, which is a 20% damage reduction against your physical damage (as opposed to 35% if you had 0 lethality).
I think you now see that Lethality is way more powerful against champions that don't build armor items (), as opposed to armor-stacking tanks ()
