Now, Surf's emphasis on the matter about it being just badass looking seems quite right. It is a thing more likely to happen in them movies than in real life, yes. But then again, it is an action every human with it's entire set of limbs can perform. And if we're not considering to make the dual weild our new shining hope to balance SGs with BGs, then we'd at least need to consider increasing SGs damage, or SOMETHING. All in all, I'd still give a +1 to dual wield.
