Good to hear. I was about to get pretty upset over them flubbing up something this simple. It is weird that it is a setting you have to turn on though. It looks like if you hit the button in game to go to ironsights that they would assume you wanted to aim with them. I mean, if you want to aim with the reticle, you wouldn't go into ironsights mode, would you?
Well some people like the feel of ironsights (It zooming in and holding the gun up), that more realistic, possibly immersive feel, without actually having to use them. Plus if you were making a game, and thought. Hmm, people mostly want A or B, but we also could very easily add choice C. Wouldn't you add C (Aka, ironsights as seen in the videos) just to please the people who would want that? You can never, well, rarely, have too many choices in a videogame.
