Vlad's q is bugged, really bugged

Tried to post it on reddit too, but didn't get much response so I figured I'd post it here.

Vlad's q is really unreliable right now, because sometimes when you enpowered q something, it will just act like a normal q, with the low healing and damage.

The first 20 games or so I didn't think about it, but as time goes on I get more and more annoyed with it and start to notice that it happens ALOT. I think it happens if you spam q as it's going off cooldown, maybe the crimson rush meter hasn't filled up 0.1 second after q is off cooldown or something. It has killed me several times and denied many kills I SHOULD have had, I've watched my own replays and everything, super annoying.

Also, if you q a creep that is about to die, your q goes off but doesnt heal or deal dmg, and then it goes on cd, like u hear the animation going off and all, but nothing happens and in combination with your passive being up, this can really make or break a lane, because not only will you have a cooldown on your q, your crimson rush will be on 0 too, so you wont have your passive for a long time.

The champion is completely broken right now and I don't think I wanna play it until it's fixed, play 1 game of vlad and you will notice it, the q cooldown bug is old tho, it has been around ever since i started playing him in s2.

Edit 1: Forgot to mention, graves smokescreen cancels your q too, making it go on cooldown without doing anything.
