A lot of ragers on your build. I would encourage you to be more in depth and include some video to stop the trolls. You get a +1 for going outside the box and a congrats for using the combo. I would however like to advise some changes in terms of how you play early game. Rumor has it (from me), that someone (me) loves when those AD carries overextend. Check my build out (Singed and Volibear) and maybe talk about possible countering to other champion selections as well, like the taric+ AP burst everyone has a hard on for.

Even if you "win" the lane (More overall money) you will have two underfarmed carries. It may work in normal games but in normal games anything could work. I used a support Leblanc and have sucess, but I know that it is a terrible idea.

-1, sharing the cs may work with different characters, but not with two carries.

I could only see this working in very very low elo games, normal or ranked. There are so many reasons this combo is bad but I'll stick with the obvious ones. First of all I would never rage over such a combo. Wanna play it cause you think it's fun and you're good with it, go ahead.
Let's say you don't a supporting support cause all your other teammates play more than good, ward properly even your side of the river etc etc etc. But.
You don't seem have taken under account the cc's of the other lane duo or the enemy jungler. Your ward is way to near to escape a powerballing Rammus for instance, you'll sure see him but you won't avoid him. Whatever the case a taunt, a slow or a stun by the jungler and a simple focus from the enemy duo should bring down at least one of you (and this doesn't even need skill, since the escape mechanisms espacially on ashe are... well are there any?). In early game you may harass and push better than anyone, but you're two freekills for a proper team with a junlger/roamer/pushing mid, even a sinlge teleport.
Besides that, now people know how to farm under turret. Even if constantly pushed, the enemy carry will get the cs and from what you're saying, it won't be that far behind than u2 ad carries (since you're splitting the farm).
Which brings us to, why split the farm? This is not even math. The more you get the better, either this is kills, assists, cs, w/e. Why don't let one AD carry be super strong instead of having 2 equally farmed ranged ADS. Since you're playing this, have you ever tried playing Ashe as a support (which would be a terrible idea too, but at least she's got some utility)? From what I'm seeing, now you need more than a B.F. or a Latern on your second return to the base and I can't see how two farming carries can do that.
Armor has also become incredibly cheap these days...

This is just a tactic to pwn some noobs. AD carry + support beats the lane easy if theyre smart or a ap carry + support because you cant heal yourself like they do and you gotta leave the lane or die if they are smart they wont feed and you have to share cs (and you cant cs well against a support with heal) so its not good against good players

My arguement is relatively simple. How do you get fed and what does it mean to get fed?
To get fed is to have a higher gold accumulation than other members in the game and so be able to get stronger items and be able to easily take out competition. So, with this definition, getting fed does not mean getting a high CS, it means getting a RELATIVELY high CS. That being said, if Caitlyn and Ashe combo can stay in the lane and deny CS to the other lane combo while getting kills without giving up any kills, than the combo will work because the 2 will have gotten gold from a combination of assists and kills while getting the occasional minion and the other lane combo will not get the same opportunities because supposedly, they are not in the lane long enough to get a lot of gold or make up experience.
Now, I have not personally tried out this combo, so I don't feel like I can vote, however I think that the theory is relevant, but risky since a large part of your success revolves around getting early game kills.

this guide is bad cuz
thornmail will tare them apart

thanks :) At least someone got the idea :D

+1

i dont care **** abt ppl talking about team composition theories. if you are FAT. you win. of course you gotta be reasonable. generally putting 2 carries is bad. but if its both range . i think its good. kills grant gold for the killer and the assist. so its a win win. personally i am a caitlyn player. she is a amazing pusher. with ashe. they can dominate lanes without being afraid of getting ganked from mid. with that say. i think this duo is good. +1 man . peace

Just because it makes sense to you doesn't mean its good.

If it not makes sense to you, it doesn't mean it's not working. And i told a lot of different situations, not just wait in bush, and we played not just 1 or 2 games with such combination, but like ~30 and we owned the combination support+carry, support just couldn't guard carry enough because of our damage output. And if you are good, you will manage to last hit + harass and kill at the same time :) And how can you judge if you haven't tried this out? :D Why people are so negative about uncommon combinations :/
