Giving Ashe back her power to be the anti-mobility carry.

New Debuff: Slippery Ice. Enemies who are effected by slippery ice and attempt to use a dash get stunned for 0.75s.

Ashe's W now creates an icy field on the ground for 2 / 2 / 3 / 3 / 4 seconds, enemies who stand on it get debuffed by "Slippery Ice". This effect is renewed every second for enemies standing on the frozen terrain.

Explanation: With the introduction of slow reducing masteries and boots Ashe has falen far behind. The fact that everybody and his has either resetting, low cooldown, or just several dashes completey ruins her ability to control enemy movement like she used to do. Havign the worst DPS among all carries I think it's far to reinforce her ability to control high mobility champion and possibly make her a viable counterpick for several enemies.
