I find it I am not dexterious enough in real life to be using both triggers for combat (yeah I am a clutz in real life) but it seems if I dual wield and just swing with my right weapon, I do more damage than I do with just swinging with my right weapon with no weapon in the left hand. So this got me thinking dual wielding is just for looks but not sure about this.
So how does dual weilding actually work?
