To me it seems like they are actually in a weaker spot than most roles. Wouldn't you rather have a 5/0/0 Leblanc, Darius, Yasuo, Hecarim, Zac, or Katarina than a 5/0/0 Twitch, Cait, or Vanye? Because any good top, mid, or jg should be able to 1 shot an ADC and eliminate them from a team fight.
It's just the current circlejerk, there will be a new one soon. It's on kind of a rotation.
League of Objectives is dominated by the class that is best at taking objectives.
it's really that simple.
At the moment it is because supports have been given the tools to protect ADCs, and assassins have had their assassination windows lengthened. This means that assassins aren't able to be credible threats to ADCs. Couple that with the damage creep new masteries provide that ADCs get better scaling out of those stats and the end result is part of the reason why bot lane camps are more prevalent.

People hate dying in this game. So they blame ADC which is a symptom of what has occurred during the preseason of which tanks and supports are now able to dish out large health pools worth of shields. For which in reality ADCs in general are extremely easy to counter their damage with 4000 gold with ninja tabi and any other armor items that gives 50 armor. Being able to effectively reduce their dps on most tanks by 60 until an ADC has finished 2 core items+ boots normally around 7.5k gold before they can get a last whisper for another 1.3k needed around 8.8k gold to be of any use to a team. In general most people hate dying instantly. (I have a full 40 armor rune page at lvl 18 along with defensive masteries for surviving burst on ADC) because ADCs in general are forced to buy damage or be irrelevant to the game.
Also, Assassins are credible threats to ADCs. Just they suck at everything else.
Not with these around:
Vayne and Twitch are overpowered. And yeah I'd rather have them than those, except maybe Hec.
Its literally 
ruining games left and right. The rest are fine. Also a few of their items 
need nerfs as well
I'd like to see another carry class able to lane bot lane, either solo or duo with support.
Might as well be honest.
Whether or not they're OP, I'm unsure, but the entire game is kind of balanced around their existence.
I would take a 5/0 adc over anything else because right now the meta is the jungle or mid get fed and then bot lane gets fed then top is fucked because its only pressure in lane is splitting and maybe using the god awful tp so they probably arent carrying . and god no i do not want a 5/0 zac because the only thing he will get is more tanky and still do the same damage
the only ADCs that are problems on their own are Twitch, Vayne, Cait and Jhin
the rest of them are propped up by their supports and their absurdly good items.
