@Riot, Jhin's Passive

Riot, you finally have the opportunity to help remove a champion's cookie cutter ADC buildpath through their passive, and instead you make it so that the cookie cutter ADC build works just as well on Jhin as it does on every single other champion.

Jhin's passive currently means that AS increases don't increase his attack rate at all, but instead when Jhin crits (including on his 4th auto), he gains bonus MS. Sweet, that's unique. He attacks at a static rate all game. That's cool. I read on, then saw this.

Jhin's AS increases his AD

I'm sorry, but WHAT WERE YOU THINKING? You tried this with Azir and his CDR/AS passive, which you eventually got rid of entirely and put onto his W. You HATE conversion passives, and honestly, either the effect is powerful enough to make it worth while so that he ends up building 3 AS items and IE or is so weak that the only AS people will get is Beserker's and Yomouu's Active.

Personally, I missed the AS->AD conversion passive at first and was frankly kind of excited at an ADC who's buildpath would have been IE->BT->Mercurial->Yomouu's->Boots->Mortal Reminder or some variation of that order.

I was excited because, he got a 4th attack that was a guaranteed crit, AS not affecting his attack rate meaning that it wouldn't be a good purchase on him, and his Autos needing to really pack a hyper powerful punch, but no, you added this AS->AD conversion passive.

so the question I have is:

WHY?

EDIT: I'm complaining about Jhin's AS-AD Conversion passive. Riot has gone out of their way to remove Conversion passives whenever possible, They removed Kayle's AP<->AD passive years ago, they removed Xerath's AP->Armor passive with his rework, and want to get rid of Galio's MR->AP passive eventually too. They eventually Removed Azir's CDR->AS passive as well and instead just made it so he get's a flat %AS per rank in W instead. Riot has never gotten a Stat Conversion passive to work properly. it's either so OP that it locks a champion into specific builds that if they leave the build, they're doing suboptimal and it's incredibly noticible, or it's not noticible and simply optimizes champion's build paths without affecting them in a meaningful way.

Vlad's HP<->AP passive is one that historically was so overbearing that when it got nerfed, it's simply made it so that he favors HP/AP items a little bit more than he used to, but he essentially builds what every other mage does that likes to get Tanky AP.

Eventually Jhin's AS->AD conversion WILL get nerfed, or removed. it happened with Azir, it'll happen again.
