I have to agree with lockdown6435 here. Your attack speed may be extremely high, but you don't have the raw damage to make it worth it. A standard carry Ashe can hit for 400+ damage per shot quite easily, and although she may only manage 1.4 attacks every second instead of 2.5, she deals a lot more damage in the long run.

Consider that with your current setup, you have 205 attack damage. Your masteries do give you 6 armor penetration. Against a very squishy champion, such as LeBlanc, you reduce her 75 armor at level 18 to 69. Your 205 damage autoattacks now deal 121 damage to her. Assuming 2.5 attacks per second, your DPS against that LeBlanc is 303.

I now refer to the current top-rated Ashe build. This Ashe will probably have armor penetration runes in addition to items. A 400 damage Ashe with Youmuu's Ghostblade that has 1.4 attack speed will reach 431 DPS - much higher than yours. And you know the interesting thing? She can pop the active on her Youmuu's to spike up to 646 DPS - triple that of your own. In addition, her completed item build costs only around 14k gold - 2k less than your own. She also has Banshee's Veil, extending her survivability, and Stark's Fervor, being team support as well as getting lifesteal.

The point is, standard Ashe play far outstrips this.

Listen man, I love people that contribute and all, but this, my friend, is NOT how to build ashe. She is NOT designed to have a **** load of as/ms. First thing that made me not like this build was seeing only 205 damage. I could care less if you have a sheen, you damage is way to low in my opinion. Second thing: 2. Attack Faster Than Anyone. 3. Make Everyone Your *****. You attack fast, cool story bro. You do a rate of 410 damage in 2 seconds, whoopie. Were as a carry ashe can do around 800+ every second. This build might be designed great for smurfs re-leveling in the lower stages of gameplay, but this build also requires 16685g for it to be successful build. Its fun to roll high attack speed ashe, and movement speed, but then again, shes not being utilized right. Sorry if i sounded mean, but this if just my opinion on ashe, and im just saying try building a carry ashe instead of for the lulz non team helping ashe.
