Grenade launcher for heavy. It would fire some kind of elemental grenades and have a decent fire rate, maybe 6 shots to a drum but Carry only 2.5 mags worth of ammo max. For secondary I would say an smg type class. Decent rate of fire fairly low impact, and short range. That way players that use things like hand cannons and scout rifles would have a full auto option for when overwhelmed. I imagine it would have a fairly small(25ish) magazine but a decently fast reload. I definitely don't think it should have much of any range though. For primary I am at a loss.
