is my jhin build good?

I'd replace your second zeal item with . The CDR and mana regen is really helpful in the mid/lategame. I usually get because the range increase is really good on him, but if your team is really struggling with waveclear you can go Shiv instead.

you should never ask these people that question0. They will go on about how bad you suck now!

Nah, too much attack speed.

no use probuilds

Flat AD scales better on Jhin than any of the items do. Getting one of them is fine for their unique passives (I prefer for the range) and to flesh out some crit for your first 3 attacks but anymore than that is inefficient.

I highly recommend getting both and as quickly as possible. The CDR is phenomenal. Also, out of all the zeal items, I find that is one of the most helpful for the movement speed and the extra bolts, which can make a nice difference in team fights. In my experience, you want AD > crit chance > attack speed. Attack speed just doesn't boost your multiplier as well as crit chance, and the multiplier itself isn't good without high AD in the first place. There are certainly benefits to having 100% crit chance (like consistent damage and that movement speed boost), but make sure that you don't neglect your AD. I wouldn't build more than two zeal items in any situation. Other than that, your build looks pretty solid. Once you've gotten your core items, decide from there what is most important to you.

should prob be removed. id replace it with

first item should be either or .
