Can Ashe get a rework on her Q and passive?

i feel like Ashe's Q and Passive needs to be changed Her ult is great for stunning, E is great for vison on the map, W is great for poking and damage but i fine her passive to be a bit weak (once focus reaches 100 stacks next attack will crit while out of combat) because while fighting you cant use it and when entering late game you'll be able to get crit items like or making her passive almost useless and her Q which applies a slow to your basic attacks which i dont remember using that often i feel like her passive and Q should switch like her passive should apply a slow to her basic attacks by a very slow amount just like and her Q should be an ability that should have a 100% crit with a long cooldown whats your guys thoughts on this?
