It seems to me that the mechanic for dual-wielding introduces too much specificity into an abstract system. People are using "dual-wielding" with Brawl, arguing they can because they have multiple limbs. This seems game-breaking, and dual wielding should be remove from general consideration. It's far too easy. Even Saga required a couple of precious Feats to become remotely effective. If it needs to be re-introduced, do it through Talents in specific specialization trees.
I'll paste my argument from a thread I hijacked
(sorry HappyDaze)
What if you think about the dual wielding fists as using your fists and your feet?
That's missing the point. All this is already factored into the Brawl skill. If you connect, you narratively explain that you send the other guy flying with a left-right combo to the face followed by a kick to the solar plexus. Everything else is dealt with that way, why not this?
It should be the same with melee. A wookiee is wielding a vibro-axe? Okay, he does 9 points damage..."the weight of it and the power behind it crushing through the stormtrooper's armour". A Duro is wielding two light sticks? Okay, he does 9 points damage..."the flurry of blows finds gaps in the armour and leaves the stormtrooper's helmet ringing." Any bonuses (e.g.: defensive) would be part of the weapon quality.
Note there is only one Brawl skill, only one Melee skill. You don't get penalized for unfamiliar weapons or styles of fighting because it's an abstract game. By catering to the "dual-wielding" crowd, they destroyed the abstract narrative, encouraged meta-gaming.
Ranged shouldn't even give a bonus, unless maybe the character takes some expensive Talents to train with it. I wouldn't have too much problem with it at that point, if it cost significantly.
Jet Li has fought in some scenes with one hand. He keeps his other hand in his pocket.
So Jet Li got a couple of setback dice, but he's so good it didn't matter. He doesn't add attacks because he has all his limbs, he suffers difficulties when he can't use all of them.
