What if it was its own weapon? What if it bounced off walls and enemies!? What if you could pick it back up off the ground like the sandman ball soyou don't have to wait for a recharge!?!
IMAGINE IT THOUGH. I would use the frick out of that weapon.
Through making up random BS I've somehow created a weapon idea I actually really like.

(Rough stats) Pls judge me
Throwable item, takes up secondary slot. Longer arc.
30 base damage
Bounces off enemies and walls
~Positive stats
+1 ammo
+5 to 10 damage after each bounce
Each consecutive hit stuns enemies for +2 seconds
~Negative stats
+5 second recharge time
No random crits

Alternatively I could also see this being used as a melee weapon but whatever, I wanna see this in the game :V

I wouldn't mind this.
