"Additionally, I continue to challenge you to find an article where an rioter says "Lethality is not meant for/should not be build on adcs." Just because Lethality was created with assassins in mind does not mean that the use of lethality by adcs is an abuse."
The Quotes I gave you, state they were intended to help ASSASSINS. They weren't changed to help ADCs.
"Now to address your issue with the rise of jhin, varus, and mf with current lethality builds: No matter what the state of the game, there have always been 3-4 dominant adcs"
Your right every role as had dominant elite picks every meta, but never have they been so one sided before down bot lane. Those 3 are actually pushing the others way and far away. Ya they still get played but they don't do nearly as much as the other 3 at dam near every stage of the game. Twitch sneaks up on Jihn, opens up from stealth and Jihn looks at him and 3 shots him like "oh you a late game Twitch?"
Your right they get a lot of safty from being far away, but I mean Cait, Jinx, and Trist (3 champs with good AA range (Trist late game)) still don't do nearly as much.
"Side note: Pantheon is absolutely an assassin. Play him more, you'll see. He's just a less sneaky assassin."
Panth is classified by Riot as a Diver

"Addressing your claim that ADCs shouldn't be relevant until 30 minutes: This is absurd and exactly the reason why we saw people playing ziggs bot lane immediately before the lethality buff. ADCs should have the late game build path as an option available to them, but should also have a build path available with a trade off in late game power for early game strength. Most games are decided significantly before the 30 minute mark and most of the time spent playing afterwards is just going through the motions of winning while the enemy team sits in denial that they've lost. If ADCs can't be useful before this point, then people may as well go back to playing ziggs bot."
Yep I agree, doesn't change the truth now does it?
Cait, Luc, Corki, Ashe, MF, and Draven are your ADC lane bullys, even before this season or the one prior unless they got fed AF they were still weaker then their counterparts - Top/Mid, some Junglers
"Additionally many of the champions you say are too strong with lethality are also building BC. Again this becomes an over-tuned interaction between BC and lethality and LW items and lethality. J4 has the additional abuse of armor reduction in his kit. This is also the abuse you can see when watching Sirhcez play lethality garen. He has an on-kit armor reduction which is basically a free BC passive which is entirely too strong with a lethality build."
Although I've always enjoyed full AD assassin J4 top/mid it was never a problem up until a couple of patches ago, he used to full off, now he doesn't, he just one shots in AoE form.
"My suggestion is to change where it is calculated into the armor reduction order-of-operations. This way you can allow the stat to be strong by itself, but not over-tuned when combined with other items providing armor reduction."
If you've ever read any of my responses about the topic from the last couple of patches I've been saying exactly this, I don't care that ADCs use the items, I don't, my comment here though was that it was meant for Assassins, which is was, it was already mentioned above, I gave you quotes from a RIOT post stating that the Lethility changes were meant to give ASSASSINS a better time. Instead of challenging me to find you posts go fucking find some stating they were for ADCs and post them, I've already played that game with you, its your turn.
Also I never once said ADCs should build Leth, I said I read the 1st paragraph and saw Leth was changed for them which is false and stopped reading. I said Leth was ment for assassins, BC for bruisers, and LW for ADCs.
I don't care if ADs want to build Lethility, but it should be at the cost of being able to build LW/BC. Ever think it went from Flat Pen to Lethility was because Luc, MF, Varus, and Jihn were all doing the Korean build?
Luc made this popular last summer, Ghostblade into Cleaver picking up a Maw, PD, DD, LW, IE, shit like that. You give bruisers and assassins nice items and ADCs will ruin them for you. Ezreal is notorious for breaking other role/chamipons items.
