I like to suggest that the fixed wiev during loading is being an optional choise. Holding the left-Alt, to force the wiev somewhat away, to keep the awareness around you, is a bit anoying.
Its also unrealistic ... Any trained soldier are able to load, without looking direct at the doings.
I cant count the times i have been stabbed, during loading, caused by the lack of a natural posiblity, to keep an eye on the suroundings.
