I made a thread about this without seeing this one. As I stated in my own thread, the main problem with the sights is that it doesn't represent the method of shooting with both eyes open. If you aim down your sights with a ghost ring, and keep both eyes open, but focus on your front sight, the rear ghost ring becomes almost invisible, and makes it quick to aim. If this would be modeled in game, I would be so much happier. They may have left it like this for balance, but it doesn't seem like it. It may have just been something that they didn't consider. If, however, it was for balance, because the Americans supposedly get better weapons, like Fisher said, having so many Japs with SMG's defeats that purpose.
