I have a lot to say about this build because i main Jinx and played her the minute she came out. Now a lot has already been covered above, and i STRONGLY agree with Vynertje, NEVER rush attack speed you also have "Ninja Tabi"?!?! No no no my friend, never ever on a adc, she needs Berserker's Greaves. I also agree with Maintained in that Atma's Impaler should not be a option.
This is a example of what your builds items should be - Berserker's Greaves, Bloodthirster, Phantom Dancer Phantom should be purchased 3rd, Infinity Edge, Last Whisper and Guardian Angel. On a side note the build does look extremely nice though.

After updating your guide, your build wasn't much better, sadly. You must always go Berserker's Greaves, its the cheaper and most efficient. Atma's Impaler should not be an option. You won't get good stats from it without lots of health, where as you have no health items at all. You should take either Bloodthirster or Blade of the Ruined King and replace one of then with your Guardian Angel.

Let me explain you the math on AD carry steroids:

If you get free attack speed, every added point of attack damage has a lot more value.
If you get free attack damage, every added point of attack speed has a lot more value.

That is why you NEVER rush attack speed on a champion that gets free attack speed.

Honestly, I would go as far as saying that, even though you made the guide look really nice, you should not be writing guides because you lack the knowledge to. The final build looks terrible and if you ever wanted me to tell you everything that is incorrect in this guide, it would come down to me making the guide instead of you.

All very helpful comments, thank you! I will be editing the build here and there, and testing it in games to make sure it works well. Keep the constructive criticism coming! :D

While I was going to state a lot of the same things with Maintained (see above)
I couldn't help noticing that you are actually under level 30 and therefore not capable of ranked play. I can see this with the differences between your gameplay and current meta.

• You haven't actually explained much about summoner spells, people consider taking Cleanse and Barrier for ADC's and you haven't explained why you prefer ignite over them.
• Also if you need armor penetration, you should pick Last Whisper for it, cleaver is very stack dependant.
• I like how you brought Executioner's Calling into your build, but it's not really an efficient early item as it isn't worth its stats and is effective against only when opponents have sustain. There are lots of other crit chance items you can consider building.
• Sorcery from offense tree in masteries? Is it really worth it? Jinx's cooldowns are relatively low already, and you're basically wasting 4 points on it instead of spending it on maybe more health on defense tree; as you stated in the guide, Jinx is squishy and could use that extra bit of health.

I don't want to be too negative on this guide, you had some good points aswell. Just work towards better explaining and bring up those alternatives to your own gameplay.

A few things I would like to address;

• Your cheat sheat is a little messed up. You need to mark your core build.

• You have hardly any attack speed, that means when you have to use Fishbones, the Rocket Launcher, you won't be effective.

• You have no defensive items, really discouraging. You need one!

• The armour penetration from Black Cleaver is not reliable on Jinx. For example, when you snipe someone, they would have no stacks on them, won't take much damage, especially late game.

• You took Ignite with Executioner's Calling. A big no.
• Gameplay is under explained. You need more details.
• You didn't explain your masteries. So how are you going to convince the viewer that you should go 26 points in offense?

Good stats doesn't mean its viable. Hope I convinced you. Good luck! ^-^
