Question to ADC mains: Why do you insist on...
...getting yourself in a position you are prone to being initiated and blown up within a second, just so that you poke a person of the enemy team for like 200 dmg, sealing the fate of a bad teamfight where you will be out of the equation from the start?
I'd say quite comfortably that when the stars align and you have a competent jungler (or both teams have an incompetent one), this ADC behaviour is the #1 reason why the mid to late game lead push gets thrown out of the window.
jumped at me from 5 miles away when I was behind my entire team, totally my fault
