This thing being spammed would be worse than a regular missile. Imagine, somebody throws it in a combination with the rest of them, and suddenly they don't have the energy to fire even their Justices. And they keep mashing Q, so you're potentially stuck without guns for a good seven minutes.
If such a thing were implemented, it would have to be dumbfire, or leave the energy at perhaps 25%; enough to fire guns, but not enough to mash Q. Dunno. As is, it just reeks of perma-disable imba-ness to me.
