This pisses me off to no end and I'm done not complaining about it.
Ashe's W.
When her Q is active, her AAs "click on" and the regular arrows turn into ice arrows. However, Volley sends out an arc of ice arrows... regardless of if they're actually ice arrows or not. Which means with no Q at all, they all look like ice arrows when they aren't.
There's literally no logic possible to justify why it's like that. There's no reason for volley to possess zero logic and not properly send out regular arrows when applying Q to that W is not possible.
