Simple change for Ashe's passive
I think most people can agree that something needs to be done with Ashe's passive.
My suggestion is rather simple: Alter her passive so that attacking minions (normal and cannon) does not stop (and restart the timer) her passive from stacking, nor does it use the critical strike on them (large/epic monsters will still function with her passive as they do now).
Just my idea to give her more use and functionality out of her passive.
