Lethality changes. Half for ranged?

As the new patch rolled in for the lethality changes, it seemed op. As an ADC main, I now build lethality in almost every champion. For an example, Lucian, Jhin, Ashe, (Yes Ashe. You should try it.) and even some top champions have been now going full lethality. Ex. Riven, Yorick, Fiora. I just played a game where I was a full hp Lee Sin with semi-tank items. (Dead Man's Plate) A Jhin who was 3/1/3 auto'd me 4 times and I died. Keep in mind I was 6/4/3. Now, I'm not saying Lethality is broken, but it should be nerfed for ranged characters. Any opinions?
