Nope. I can't. Just a suggestion, the shocklance is nice. As for the whoring part, it's most likely going to happen that way, unless they're really good with whatever melee weapon.
By the way, I assume the melee weapon will still rely on aim, and will require effort to use properly?
Oh right, I'd like to respond to that smoke grenade. I'd say more grenades, different varieties, is overall a nice idea. But, I don't exactly understand what you mean by invisibility. Whoever is caught in the smoke grenade should be blinded. The person who threw it shouldn't be immune, and should still be afflicted by it. The length of blindness can depend on how close the people are to it.
