were also the only role that cannot 1 v 1 bruisers and mages unless unbelievably fed without insane outplay and even then its unlikely. everything in this game is designed to instantly explode us or kill us over an extended fight. we cant tank a true tank one on one until late game, cant take bruisers cuz they will melt us before we can do enough dmg, and mages just explode us.
adc requires absolutely prime positioning, decision making, and believe it or not...there is skill in self peel. a good adc will have some combination of bork, bt, mercurial, etc to help peel for themselves when shit gets bad. adc is the most unforgiving role in the game in that if you make the slightest mistake you are gone and your team probably loses that fight.
sure, its not as mechanically impressive as say a lee sin doing an insec, or a yasuo outplaying 1 v 5....but it is just as skill intensive as the other roles. it is more dependent on your team, but a good adc can overcome bad supports and teams.
