Yes you get a one second CD Q. For a brief time. At level 16.

And each one doesn't actually do that much damage on it's own, AND it's a skillshot that can be dodged (one second CD, so applies Rylais 15%).

Of course your DPS is high with your ult at max rank, it's an ultimate for a reason. When playing against him, you'd want to bait him into overloading and then engage while he's silenced or directly after when he has no charge.
