Godly attack speed for Wind Piercing?

I've done some extensive observations and noticed 2 things:

1. The animation is normal on other people's screens
   
2. The damage dealt isn't shown every hit that makes contact. There were moments when the archer wasn't shooting Wind Pierce on my screen, but the BF showed KB animation on my screen despite no dmg was shown on my screen.

Conclusion? It probably deals with itself between the user's client and the servers (representing other users), without properly displaying all the results. I'm guessing, yes, it in fact is dealing more damage than it's supposed to be.

EDIT: Upon review and further observation, the KB frequency on Typhons seemed to fit the Animation frequency on an alien screen, which means the damage registered on the Server shows no abnormal increase. It's only a visual bug on the client's side.
