You make no sense and talk like a 12 year old. In Planetside 2 we have freaking computer implants in our brains that enhance our targeting and firearms proficiency. There is no way you can say it's "scientifically" proven that dual wielding in this games setting would always be less profitable. We also have battle helmets with electronic HUD's that project data from those implants, and other sources, directly into the eyes of the soldiers. With this kind of technology, it would be pretty freaking easy to target AND fire on a different target with each gun - with great accuracy. We're supersoldiers! Not some dumbsh$#t high-school dropout in basic training. And honestly, realism? We're playing a game where you can die and be re-spawned, and retain ALL of your memories and knowledge somehow. Yeah good luck using "science" to explain how that could ever be possible.
