I'm not sure about you guys, but in the last few patches I haven't experienced this "ADC Meta"
While they are picked every game, they have been doing significantly less damage due to the abundance of assassins and divers that just murder them before they can do any damage. I'm not saying t hey're weak, i'm just saying that I haven't experienced this ADC's rumored level of power that the boards keeps going on and on about. Champions like jax, kha, and camille are in the meta, with fizz, kass, and other assassins being common picks in mid. These are champions who can overkill extremely squishy champions, so unless the ADCs are ahead, they have to be super mindful of their positioning right now even with their support standing next to them.
If their support dives? Free dinner. They can't really 1v1 any class in the game besides certain tanks unless they're ahead, or are
(assuming everyone plays it optimally), therefor if their ali wants to go in, they can't do anything at all, leaving room for enemies to go in.
ADC seems pretty balanced in the meta right now in my experience, at least in plat and below. I can't speak for diamond+.
