What if the Unknown was like the Halo: Reach grenade launcher?

Tap to Fire: The UVX explodes on contact. No bouncing or awkward angles, it just explodes the second it touches a surface or a Survivor.

Fire and Hold: The UVX projectile becomes 'rubbery', and bounces all around, which doesn't explode until the Fire Button is let go. This allows you to perform trick shots as normal, BUT can also let you leave the projectile on the floor, dormant until you let go of the Fire Button.

With the Unknown having the poor reputation of being "The Harmless", I welcome any and all changes that might help his overall play style or strengths. This is something I've had in my mind forever.
