Dear wood 5 
player, or any player with 1.5 brain cells, Ashe's new kit works very well with attack speed. This does not mean that rushing 
and then 
is a good idea. 
is still what you build. if you don't like it. Just please build with some common sense. Look up a guide or something.
Sincerely, your 
that hates you.
TL:DR I've seen an influx of feeding Ashe players that build only attack speed. Please don't do that.
But you always build . Because it is best item.

I'd recommend attack speed runes instead of dmg and rushing 
as your first and second item, then get 
then get for the crit chance and attack speed after which you get a and another then get furor enchantment for boots
I only get armor pen if the enemy starts building a lot of armor
I played against Ashe players who build shiv of runaan's first and they always die to me
fyi
gets triggered a lot by 's Q
Although each one of the additional arrows from 's Q won't proc 
Each of the many bolts from will proc
's Q will shred the person you target with the aa, all the while and are shredding the tanks on the side.
PLUS throw 
instead of a 
will set you up and apply your passive to other targets. One shot from 's Q with the bonus arrows will fully stack BC onto them, and if you have , the flurry of bolts will fully stack anything else she hits with .
That's a guide to late game Ashe.
Still gotta rush . Always get damage over attack speed first. It is much more cost efficient with her passive anyway in the early game.
Yeah, Ashe still scales so well with the standard ADC build that rushing Hurricane is really, really bad. Only build it if your team needs the waveclear or your opponents consistently stand close enough together that you'll get all three hits off. Even then it's probably better on a glass cannon build in place of a defensive item because IE + another crit item is mandatory. There just aren't enough item slots for it to be core because you need stats other than attack speed.
EDIT: I've run the math. The AD scaling on autos from her passive only pushes the amount of AD you need before crit chance becomes more gold efficient up by about 10 AD. By the time you have a BF and Pickaxe it's time time to switch to crit.
Interestingly enough, the meta build on ADCs is meta for a good reason.
Tl;dr: Build crit unless you're kalista.
