Ashe Bugs
First off, her W is supposed to increase her slow the same way her crits increase her slow. It doesn't do this.

As you can see, the slow isn't being applied when hit with a Volley. Furthermore the tooltip says the slow is doubled at all ranks with a crit or a Volley. These screenshots also shows this is untrue.
I also want to note that I was under the impression that Ashe didn't crit. I was under the impression that an Ashe crit was every auto attack after Frost Shot was applied. I think a lot of people are under that impression as the most popular mastery on Ashe is Warlord's Bloodlust. Considering Ashe's crits only deal 1 extra damage, taking Warlord's Bloodlust on Ashe is incredibly inefficient. It's the most inefficient mastery you can take on any champion who deals crits.

Here are a few screenshots to show an Ashe critting.
