Ashe Buff
Okay some simple things for Ashe that I think could be nice for her (these will be direct buffs, one being a change to make her better against mobility champions while non-mobility will be roughly the same)
Focus (Passive): Same thing but an added context to it as well: Executing a minion will grant 6/7/8/9/10 Focus stacks; gaining a kill or assist will grant 100 Focus stacks.
Frost Shot (Q): Toggle Ability; Cost: 8 Mana per basic attack Toggle ON: Ashe's basic attacks slow her target by 20/30/40/50/60% for 1.25 seconds [from 15/20/25/30/35% for 2 seconds]
Focus change does not change anything about Focus, but it does add more incentive and reward for properly last hitting. Frost Shot change ends up being better against mobility with a stronger slow % and better for the game overall with a lower slow duration so now non-mobility that has something like a stun can potentially now get away from Ashe while the stronger slow % allows Ashe to be the strong kiter that she is meant to be.
Hope you like the ideas! ~ Stacona
