I may have totally misunderstood this, but isn't the zoom view what your vision would really be like, and the unzoomed mode we have now is a concession for the limited field of view that the zoom gives?
If that's the case, I'm not sure why people don't use it unless it's some kinda joystick inconvenience thing. Because there are certain distances where only with zoom you can clearly see the aspect of the bandit, and are able to see a break to the left or right, climb, whatever... which helps you get into position. It would be crazy not to want to see what the other plane is doing unless this view is either unrealistic or its too troublesome to use zoom. I mean, once you get in close enough to be tangled up - zoom is useless and uneccessary anyways.
So... why are those of you not using zoom, not using zoom? Am I wrong? Is zoom unrealistic? Or is it some key mapping thing? If neither, do you just not want to be able to see at distances we are supposed to physically be able to see from?
