Ashe Q - What's the point?
I'm having a little trouble understanding why Ashe's Q is the way it is.
From what it seems, 5 arrows being fired per auto attack doesn't really serve any real purpose. It's a 20/25/30/35/40% attack speed steroid that adds 5/10/15/20/25% damage to your AAs.
It doesn't seem to have any effect on on-hit effects or on something like Pantheon's passive (which blocks all 5 arrows). Additionally, it doesn't seem like the first of the five arrows of a single shot applies frost shot in order for the other four to benefit from the bonus damage.
Is there any other potential effect to the volley of arrows besides it looking cool? I'm totally fine with it if that's the case, I'm just wondering if I'm missing out on Ashe's potential by not fully understanding the benefits of her Q active.
Thanks!
