We should make Ashe's arrows steal movement speed.

I think that it would be a healthy addition to her, plus with the way that I would implement it, would also make her e more useful to level up. Ashe is so very immobile, and playing her against a skillshot based lane (i.e. blitzcrank, ezreal) is pure torture. Even with tier 2 boots, she only has 385 movespeed, so I think that this buff makes sense. The only problem is that I'm not sure if we should make critical strikes give extra.

FROST SHOT: Ashe's basic attacks and abilities apply Frost Shot Debuff to affected enemies, slowing them by 5% - 25% (based on level) for 2 seconds and causing subsequent basic attacks against them to deal 10% + (critical chance × (1 + bonus critical damage))% AD bonus physical damage while they remain slowed. Ashe also gains a percentage of 5%-25% (based on level) (50%/60%/70%/80%/90%/100% based on level of Hawkshot) additional movespeed for 3 seconds. This effect does not stack.

CRITICAL SLOW: Ashe's Critical strike icon critical strikes deal no additional damage, but instead double Frost's slow strength to 10% - 50% (based on level), decaying over the duration to its normal strength.

Hawkshot PASSIVE: Ashe will steal movespeed equal to 60%/70%/80%/90%/100% of the slow applied on Frost Shot. PASSIVE: Ashe uses a stock system on this ability; she stores a charge of Hawkshot periodically, up to a maximum of 2 stored at once. ACTIVE: Ashe sends a hawk spirit toward the target location, granting sight of its path for 2 seconds and in a large radius at its destination for 5 seconds. The hawk's sight is not obstructed by brush or terrain.
