Many ADCs nowadays build BotRK, which essentially turns them bruisery (gives them a slow, current hp shred and lifesteal, perfect for duels) and from then on can go damage or tanky- eg. varus can get a sanguine blade/last whisper for offense or randuin's/guardian's/scimitar for defense. Also Blue ezreal minus the spirit stone.
