Is there a champion design reason Ashe doesn't have an AP ratio on her W?

{quoted}

Her W is used to apply her passive so that your basic attacks are then empowered (based on AD, crit chance and IE)

I get that in lane it's used for poke, and you can get frostfang stacks with it if that's what you're trying to do, but the purpose of her W loses some of it's identity if you give it an AP ratio

Plus it doesn't fit her theme, her W is a very physical thing, a Volley of arrows

Enchanted Crystal Arrow will always be magical, magical=AP ratio

I wrote an AP Ashe (bot lane) guide a long time ago, back before runes reforged, Liandry's had Pen, Wits End had Pen, Guinsoos was totally different but

The guide is here: https://www.mobafire.com/league-of-legends/build/the-only-ap-ashe-build-513453

She's not a very useful support, has no CC until 6, and when you hit 6, your ult is very underwhelming in lane. Maybe it can create a successful gank, but often enemy support ultimates will provide far more than your ultimate at that time

I'd probably aim to get that^ as AP Ashe now, with fleet footwork probably

I don't think the naming scheme, or even the thematic of the ability, dictates what ratios the abilities receive -- see Tryndamere's Spinning Slash, which is definitively not magical or elemental, having a 100% AP ratio. I also don't think it's incredibly honest to pretend that Ashe's Volley is entirely physical, since she fires ice arrows produced by Avarosa's bow, and her ultimate is just a larger version of that.

It definitely doesn't rob the ability of it's "identity" which I think is a bit of a cop-out, plenty of physical abilities or non-magical abilities have AP ratios without it being considered strange. Malphite just had an AP ratio added to his W and that ain't ruinin' what Malphite is.

I'm personally envisioning this change for Ardent support Ashe more than bot-lane-APC-but-autoattacking-anyway-Ashe, and secondarily a flat AP Mid Ashe -- but I'd love to give your build a try too if the opportunity ever arises.

All-in-all though, I don't think there's a good reason her W doesn't have an AP ratio. Hoping a champ designer can tell me to see if there's something I've overlooked.

O played ap ashe support so much and this build is a joke for me, its hybrid, not ap ashe (shitty build for me btw)
