I love the people who just troll. It makes me feel so good about myself. I actually do things in my life other then sign on to a league of legends strategy website and vote down a million guides. One of the people even put in the quote section that they WANT to get banned. The world would be a much better place if all trolls just held hands and jumped off a cliff together.

As for the people who just DONT READ ANYTHING and dislike the guide because they think that their set up is better, GO PLAY LEAGUE THEN. If you don't need my advice hot shot, then go play.

I don't like the runes you chose.
I just completely disagree with the runes section being a player who's been playing Ashe and many other ad carries for a year now.
Clarity seals are really awful for ad carries, especially Ashe, who is really not mana hungry at all. I'd recommend armor seals. Also instead of flat MR glyphs, consider MR/per lvl glyphs since you won't be needing as much MR early game as you will mid-late game.
I'd also get flat AD marks to help with last-hitting, LW will be enough armor pen.
As for the build, it's pretty good, except GA would be better taken before BT.
Again, 21-9 would be better. Or 21-8-1. Since Ashe doesn't need the mana :I
I wouldn't get doran's first even with a healer, boots and hp pots are safer.
Didn't even consider ignite? It's a great spell for ad carries even with the changed meta (though it's slowly coming back to thsi meta :d)

The guide itself is very lacking. You need to make it more in depth.
You could take a look at some templates (here or here) and fix up your guide to make it more appealing.

If you even consider changing the runes and masteries, and the guide's look and depth, I'll up vote it :p
