Yknow what I think would be mad.
A Flamethrower.
But using PlanetSide's would-be fire equivalent. A Plasma flamethrower. How mad would that be?
Shouldn't work at anything but horribly short range though, and the damage should be purely over-time so people don't see it as the alternative to heavy assault. I just think it'd be cool to have one flamethrower guy in your squad, then when you reach CC, he could torch it, forcing ppl to come sprinting out.
I guess it does sound a bit overpowering though.. Humm, maybe the weapon could be made to require two rifle slots, since you're going to have to have the weapon in-hand, as well as have the tubes on your back. Then ontop of that you'll need to carry plasma refills.
Just an idea.
