ashe rework idea

Ashe is a kinda boring champ so i was thinking that instead of frost shot slowing everyone and making crits guaranteed (which is probably the reason she kinda sucks cause it's be impossible to balance), make it that she generates frost by auto attacking which increases her attack and movement speed but moving thaws the frost meaning that she loses the attack and movement speed.

Seeing as she uses next to no mana anyway, you could make frost her resource so that it would be easy to identify how much of a threat she is at any given time and would also be a cool niche as a manaless marksman (this would also be a good chance to change her stupid ass volly which is the easiest harass tool ever). implementing frost as her resource would also make it easy for people playing this concept of Ashe to see the cap of how fast they can attack and move and also how close they are to that cap as a bar directly above their character instead of a number above their cooldowns like is the case with the energised mechanic.

I think it'd be really cool to see the crazy micro that people pull of with a mechanic like this where you want to always be moving as an adc but if you know your limits really well you can output some stupid damage. This would also be a cool way to implement a way of breaking the attack speed cap too, similar to how kog'maw did before they reverted his W except it would be WAY harder to use because you'd have to stack it up and then stop moving all together instead of just pressing a button for double attack speed (obviously ashe wouldn't be able to double her attack speed with this mechanic unless it was seen to be what was required to balance the mechanic through live testing).

Obviously, with this change, her ultimate would be way too strong to be in her kit so either her ultimate would have to be changed or it would have to come at a cost of some sort like using a large chuck of any frost you have should you decide to use it for example. This would preserve her R as an engage tool but heavily discourage people from using it after a fight has already started because it would seriously hurt your damage output (keen to hear better ideas though cause this probably wouldn't be enough to bring her into line).

Keen to hear thoughts about this idea or if you think ashe needs a rework at all :).

(Edit: this would also work into her lore really well like tapping into the true power of the bow her ancestors left behind or however it goes)
