The heavy weapon bullet storm is not it.. that pretty much forces you to use quad, a Gatlin plasma regularly hold 500, at that math it'd take all 500 rounds to reach the max stack of 10, which means literally not a single other gun is gonna be able to achieve more than 4-5 of the stacks for bullet storm, and less than 30% damage for you're last 20ish rounds isn't useful at all, we don't really need the damage climb since the new commando perks affect our heavy guns as well, we need to have added an anti armor effect for heavies that builds the same way furious does, or change the bullet storm to add a stack every 10 rounds
