Just a fun idea I had. I remember back in the Sunbreaker's prime days, I would always joke about "not being able to throw my arc blade like a sunbreaker can throw his hammer". What if you could now?
The drawback, since you only have one arc blade, as soon as you throw it, your super would be gone, drained to zero. It would make it a nice way to use most of your blade, then throw the blade at the last guy who's a bit too far away like an electric throwing knife.
Reminds me of that one thing from borderlands where you throw your gun at them instead of reloading or something.

Make it a knife on a chain so it doesnt have infinite range. And they could add that you could throw it to a wall and it slingshots you towards it like a grapple. Same for enemies you could grapple on to and pull yourself towards them.
