[2022] Rapid Firecannon

I often see players buying rapid firecannon on DPS champions like jinx. I really dont get it. I understand buying it on champions like Jhin, Caitlyn etc that have hard hitting autos and usually dont auto a lot of times in a fight. But for an attack speed champion it feels inefficient. Basically with Jinx 10% of your damage gets extra range but with Jhin its 25% (Not exact numbers but whatever). I swear people are just buying it because its recommended. PD or Ruunans feel infinetly better to me. And btw im not a new player im a dia adc player but I have never understood this. Am i right or is it just a case of me having decided something is wrong because of an irrelevant factor?
