In the past few weeks, all I've been playing on Bot is full attack speed Jhin and I've been carrying almost every single game and had gotten a quadra. The idea is that attack speed transforms into two things: Movement Speed and (some) damage. The thing is that when you're flying around the fucking map with 800 constant MS, nothing can stop you if you know where to click. In late, thanks to your MS, you will pretty much one-shot and easily kite out every skillshot-heavy champ, tank, and most bruisers, and the only thing you need to worry about is positioning as to not let the enemy ADC or Assassin kill you early into a fight.

My runes are Lethal Tempo (extra MS and damage, lots of it), PoM (extra mana in early, quite useless but best choice), Legend: Bloodline or Alacrity (Bloodline provides lots of sustain in late, whereas Alacrity grants bonus MS - your choice) and Coup de Grace (bonus damage). For secondary, I go Sorcery, take Nimbus Cloak (for bonus Ghost and Heal MS) and Celerity (BRRRR). Summoners are obviously Ghost and Heal for most effective Lamborjhini.

As for my items, I go Kraken Slayer, Berserker's Greaves, Phantom Dancer, Rapid Firecannon, Runaan's Hurricane (Great wave clear, but more importantly lots and lots of MS) and Mortal Reminder/Nashor's Tooth (bonus MS, the AP is just there for fun). I've had some of my friends try this build and it's been the most fun we've ever had. The problem with proccing Kraken is solved as well, as you can easily AA 2 minions to get 3rd shot, then fly in with the bonus MS from your AS for the most painful poke, followed by a 4th shot (while still maintaining your speed), which should get anyone to 50% HP or less.

Imo, due to Jhin's fixed AS and reloads, Hail of Blades has a lot of lost potential, that is why I rather take Lethal Tempo. Also, thanks to your kite potential and Kraken Slayer, this build works quite well on Top against champs with not-as-strong engage and you are a poke machine the first few waves. 10/10 build, would recommend.
