ADCs suck early game though, and if they can't get fed, then the enemy team should have a significant enough gold lead in that lane to nullify them as a threat. When I think of "Sustain Burst Damage for ADCs" I usually think of Jhin and hypercarries (Trist, Jinx, Twitch, Kog, etc.), which is kind of their job.
Then again, I just listed a lot of meta champs. Maybe they should buff some of the lackluster ones.
Or maybe ADCs just seem overtuned right now because the other carry spots are Jungle and Mid. Jungle's in kind of a tank/disruption meta right now and Midlaners just got nerfed hard.
Huh.
