adc class is kinda in a bad spot

this is a question thread as we all know adc deals the damages and thats all they were made to do but as most of us play the adc im preety sure you all noticed that darius volibear shywana mundo vi jarwan xin, basicaly saying any meele champion with randuins omen in early/mid game is able to easily whack the floor with an adc while staying quite healthy after he finished

i could brag about the fact that adc needs at least 3 items (botrk last whisper and something for crit or dmg, without crit adc's dmg is too low to survive) to counter this one while his main task is to hit the frontline (cause its safe), but ill just ask

did anyone of you find a way of dealing with such situations where enemies buy one armour item and basicaly nulify your presence till end game?

i personaly find it often that enemy bruiser gets randuin as first or second big item, this means that i who does not posses enough items to shred a tank yet gets no chance to even fight cause i deal no damage and they can melt me the moment they touch me i could get a quick last whisper but it gives me practicaly no sht without ,ie ,pd and botrk so i still hit a wall
