Darius: His Q

I'm all fine with his Q being able to heal him. Honestly I have only one problem with his Q (and it might be because of a bug).

Can you please make it susceptible to CC?! I just find it frustrating that I stun him (as Pantheon) in the midst of his wind up and he still goes through the attack. I know it's not a channel ability, but why not allow his Q to be cancelled by stuns and other forms of CC?

Maybe it's a bug. I brought it up before but can't remember if I found it out as such.
