I prefer to carry. So I queue top. But Blindpick is much faster and sometimes I am stuck with support. But I'm not carrying or I'm not building AP. Can't there be any that has great AD scaling and can reasonably go with crit? I.e. a support who can build an Infinity Edge.
Just go Ashe support, but please don't do it in ranked.
How would this work if you actually plan on playing as a support though? You won't be farming and you'll still want to build a sightstone so it'll be a long time before IE happens. Once you finally get that IE it'll feel like crap until you get a second crit item. A support who has items in their core build like IE just wouldn't work, it's too expensive without farming creeps.
One word: no. Any champion that can have reasonably high AA damage on a supports budget will inevitably be played in another role and not as a support, because their kit would have to be padded with free stats to accomplish that, and they'd just become oppressive elsewhere because they'd have free stats and the utility they needed to be a proper support.
I don't think you know how support works.
right cuz a support who need to spend 3600 gold on damage is an idea and is helpful in lane.

grab as many souls as you can. and after getting 
, get these items.
by mid-late game you can 100-0 the enemy ADC with your QER, you have the sustained damage to kill tanks, and you're surprisingly tanky
they never see it coming. if your lane gets shut down hard you can end up being more useful than your adc LOL
That's known as a kill lane, already had a meta of that a couple times.
Ever seen AD Carry Thresh ? It is a lot of fun. People don't expect nor respect the burst damage with a stacked E passive and with a stacked Rapid Fire Cannon
. Throw in Duskblade of Draktharr 
for some extra fun.[slayer-jinx-wink]
lolno.
If you are looking for AD support champions, I'd probably recommend trying Poppy or Trundle.
They don't really want to buy critical strike chance, but they are the only AD supports I've really seen being used viably.
