@Riot "Bug"? with Azir's W

I noticed something while playing as Azir. It seems his W can be directly casted onto turrets. This won't summon a Sand Soldier but it will deal significant damage to the turret. I have no idea if this was intentional or not but I just thought I would let you guys know that it's something. I'll give video evidence should you need it.

Edit: Upon further review, I realized that this IS in fact intentional (as said by Zenon in the Azir Discussion). So, just ignore everything I just said.
