I am with you.
I have noticed that when the game was @32%, some couple of weeks ago, i was able to zoom in by hitting a single button. Now I cannot do this anymore, instead, i have to click and hold the Zoom in button for a while. This is just not right.
I like to fly with the zoom out view just like you stated, but when I am at 150 meters behind an enemy bogey, i switch to the gunsight view. It only took one push on the right button.
Now it is just painful, or could it be me who didnt find the right key binding?
