Hilariously, Shepard and co. occasionally shoot from the hip.
But dual-wielding pistols? Nah.
The scene that comes to mind for shooting from the hip is in ME2 when you shoot the Krogan guards (who are huge targets) flanking the Volus pretending to be Fade. At that point Shep shoots from the hip, and at least one of the Krogan goes down clutching his knee. Real accurate huh?
Aside from that, Shep is a marine. This has been made clear over and over again. I challenege anyone to find an image or anecdotal story involving any trained military personal effectivly putting rounds on a target using more than one weapon system at any given moment. It doesn't even have to be a duel weild situation, I'd wager you can't find ANYTHING. The only thing I can contemplate is maybe an attack chopper which fires rockets and a machine gun at the same time, but even then I think in those circumstances there are always 2 personel using the weapons, each seperately. In most if not all cases, military vehicles require the operator to alternate between weapons. Maybe someone could find a story involving someone using a jeep to run someone over while at the same time they shot someone else eitha pistol. Aside from that being a HUGE stretch of the original challenge, fat chance you even find that. You WILL NOT and CAN NOT find anything. It just doesn't happen.
Some guy earlier suggested 2 weapons was an effective supression tactic. This is possibly the only use for DW -ever. Even with that usage, you won't put bullets on target, you spray them just to get people to take cover. Then you run... For the idiots who use the "shep is so badass he can do anything" argument, I submit to you that Shep never runs, only pushes forward and kills; thus, he has no need to ever use supression tactic. Am I speaking your language now?
Take away: DW is a dumb idea.
Ad hominem: Supporters of this are dumb children who probably like the WWF(or whatever fake wrestling is called these days) way too much.
