I feel like there is so much stuff you could pull off if she could get certain AP items, and it just makes me sad too because you have champs like 
that have those random AP scalings on their main damage abilities despite being almost 100% AD.
You think you could look into that Riot? Just adding a low AP scaling to her W?
Unstoppable Monk1 votesAshe W hurts too much to make her do 50% hp damage from having full rageblade stacks, nah dawg
Mari De Bona3 votesHow is a 10-25% AP scaling going to make her W do 50% of someone's HP with a rageblade?

Fixed.
Her W has long range and large damage.
I think you are underestimating her W damage.
Mari De Bona1 votesWhat is 10-25% of 80?
So the most she'd get off a Gunblade is 48-60 damage. I think you're overestimating her W which can be completely absorbed by minions.

It's not only the damage. Did you read the item passive and active?
AP Ashe with 100% AP scaling ult and Hextech Gunblade Spellvamp obviously doesn't sound like broken burst healing. Nope.

Oh really? And 33% of 100% damage AoE is a huge difference off....
Not.
Vlada Cut1 votesAlthough a bit of ap scaling to make guinsoo's good on her seems interesting, it woumdn't be fair to let an abikity have both ap scaling and cr8t like that.
Mari De Bona1 votesAshe's W doesn't crit

Ashe's W doesn't crit
Wait WHAT?! But her description says it does, doesn't it?o_O
Mari De Bona1 votesFor the purposes of her Passive it "crits" which applies the stronger slow, but it does not actually crit so an item like 
doesn't effect it.
Zane Zephyr1 votesThey've stated before that the older champs like the ones you mentioned have "random" ap scalings because they wanted people to try different builds with them and didn't want them to be shoehorned into one build
I don't think it would be good anyway being as her W does physical damage so the damage boost would be negligible and the only other thing that has AP is her ult and AP just doesn't synergize with her pretty much at all
It's like AP vs AD corki: Yeah, you can do it, and yeah, it isn't the worst, but it's just flat out worse than AD
Madsin251 votesI mean even if they did this if you go AP ashe you are just straight trolling and deserve to be reported.
Her AD build barely has the BEST ashes in the WORLD scratching a 52% WR.
Infernape1 votesEzreal has AP scalings because Ezreal was supposed to be a mage/marksman hybrid. He has the option of going AP or AD, and all of his abilities have AP scalings and deal magic damage (except his Q but it applies on hits and will proc Lich Bane).
MF still has hers because AP MF used to be a viable build before her VGU.
Sivir and Trynd have them because "ability power" back in the early days of LoL used to mean all abilities not just magic damage scaling ones. Generally speaking a lot of older champions still have AP scalings on their kits even though they deal nothing but physical damage (Quinn, Twitch etc.). Also some champions have AP scalings on certain abilities to make Baron's buff a lot more stronger on them (Shyvana, Jhin etc.).
