Does anyone else feel like Ashe's Q is unsatisfying to use right now?

Long-story-short, Ashe's Q doesn't feel powerful. You can't activate it early for reduced effect, it's hard to get going, and even once you get it going it isn't super impressive. I'm hoping that's not Riot's intent, and would like to see it get a little love.

Ideas for how to improve Ashe's Q (any one of them will suffice):

• Increase the duration of Focus stacks so they don't fall off as quickly.
• Increase the duration of the active effect.
• Re-enable the ability to gain stacks through ability uses.
• Allow abilities to refresh the duration of existing stacks (but they can't build stacks).
• Improve the power of Ranger's Focus (if it must be kept so conditional).
