Ashe Rework - Just a thought (bear with me, I'm new at this)
Ashe - The Frost Archer
(Passive):* Frost Quiver* - Ashe's quiver charges her arrows with ice, causing her abilities and basic attacks to additionally slow enemy champions. Frost Quiver gains charges every 10/9/8/7/6 seconds and can store up to 2/4/6/8/12 enchanted ice arrows. 1 charge is used per basic attack and 2 charges are used per ability. Champions hit by Ashe's basic attacks slow enemy movement by 35% while her abilities slow by 20%. All slows last for 2 seconds. Note: Quiver Charges are not used up by hitting minions with basic attacks.
(Q): Chilling Focus (toggle) - Ashe's arrows become super charged by her bow and chill her targets to the bone. While active, every basic attack against Champions deal 1/2/3/4/5% of their current health as magic damage.*
[Edit: Chilling Focus (toggle) - Ashe's basic attacks consume 2/4/6/8/10 mana per auto attack. Striking enemy targets will give Ashe a stackable buff. Every stack increases Ashe's basic attack range by 10/15/20/25/30. Stacks cap at 3. 630-690 possible range. Chilling Focus remains for 3 seconds while Ashe is out of combat or toggles Chilling Focus off. New passive: Every rank of Chilling Focus increases Volley's range by 10/20/30/40/50 and adds an extra arrow. Total arrows from 7-12 fired. At max rank Volley gains 30 extra base AD. Maxing Volley at 100 + (100%).]**
*---Scrapped the idea for the current health passive as giving Ashe more accessible range seems to give her a better payout in laning phase as well as kiting/chasing (which she has trouble with now-a-days b/c of her AA wind-up and league of mobility. Changed Volley (see below( to it's current form but made it harder to avoid later game as well as giving it a range buff with Q level).----
(W):* Arcing Volley* - Ashe fires an array of 10 arrows in an arc, fanning out from the left to the right. Enemies hit by multiple arrows take 30% damage. Each arrow deals 10/20/30/40/50 damage (100% Bonus AD).
[Edit: Arcing Volley is changed back to her current Volley. Ashe fires 7 arrows in a cone, each dealing 30/40/50/60/70 damage (100% AD). Now functions with Chilling Focus.]
(E): Queen of The Freljord - Passive: Ashe collects a tribute for every enemy slain earning her bonus gold. She gains 3 bonus gold per enemy slain. This bonus increased by 1/2/3/4/5 based on the time in-between kills. (Every x amount of time built up). (Active): Ashe channels to charge an arrow for .5 seconds and arcs an arrow in target direction. The arrow grants vision along it's directed path and explodes upon reaching it's destination, revealing the area for 2/3/4/5/6 seconds. The detonation area applies Frost Quiver's 20% slow for the duration.
(R): Enchanted Crystal Arrow - Ashe shoots a giant arrow across the field in target direction. Upon hitting an enemy champion, they are dealt 150/250/350 (100% AP) magic damage and are stunned for 1 second. Surrounding enemies are dealt the same damage but the slow duration from Frost Quiver is reduced by half. If Ashe has more than 2 charges of Frost Quiver arrows, Enchanted Crystal Arrow will consume 1/2/3 extra charges (based on rank) and will stun for an additional .5/1/1.5 seconds and Frost Quiver will apply a 40% slow instead of a 20% slow regardless of rank.
