The player base itself is the reason adc is weak right now
Adc players need to realize that their champions actually have a weakness now (weak early game due to poor base stats) and play accordingly, instead of the usual play extremely aggressively because your champ is the best in the early, mid, and late game given a decent comp. Now ADC's are weak early game, decent mid game, and great late game. Don't try to 1v1 a bruiser (as early game class) as a marksman (a late game class) at level two and then complain to riot that your champion is "too weak to carry". If there's any class that's too weak it's tanks, which is evident by the number of assassins in the meta right now.
