As An ADC Main...
... I always honor my support.
Why:
Supports are the #1 reason why a lane can be considered oppressive. If are "big", that is not because you are a god-like adc, but it is because your support managed to set things up and get you kills. I mean, yes, you need to know how to play the champion, but the support is a good chunk of why you have so many kills.
Truthfully, your bottom lane is about who the adcs are, it is about who the supports are. In other words, it is actually a battle of supports, not a battle of the "best" adcs.
You can take an adc mid and see how differently you do than when you have a support with you.
-
The support helps peel jgs away from you.
-
They give you early game sustain (until you get some lifesteal and such).
-
They cc enemies so you can land your skillshots and other abilities.
Example:
Adcs are:
(Since she is pretty much perma-banned)
and 
Miss Fortune has
and Xayah has
.
Miss Fortune is able to deal damage and ensure domiance because Soraka is able to keep Blitz from Q-ing with her ranged silence. If he does Q and get Miss Fortune, Raka is popping heals, silencing, q-ing, ulting (if need be), etc. On Xayah's side, Blitz is able to grab someone, pull them into range of Xayah's feathers, and allow her to pop them. Blitz hard cc gives Xayah time to counter Soraka's heals... see what I'm getting at?
So, basically, as an adc (if you got big) honor that support because they are one of the main reasons you went 25-0.
