Ashe should get her (old)Q- enhanced sound effect back when she crits
I actually would not be surprised if the team is already planning on doing that, but not hearing it immediately there sent my poor little heart skip a beat. For clarification I'm talking about when you turn those Frost shots on, and every single AA has that that immensely satisfying ice crackle that pretty much provided an autonomous sensory meridian response every hit. But if that sound could come back on crits, I'm pretty sure there would be quite a few happy campers in the summoner's rift.
Oh yeah, I suppose it could also help let you know you are hitting that frosted target in the crowd of a team fight in the middle of a lane.
Edit: grammar
