but i doubt that, would need additional coding for a feature that's not necessary (also i tried the gunship in vanilla bf, it hasn't got free-look either)

Mouse Look is a necessary feature. Edit to elaborate: Currently, you have only the ability to look straight forward, straight backwards (F10), and to see a flyby shot (F12). This leaves you with rather big blind zones, which in turn means you have to actually turn your fighter to see what's, for example, at 2 o'clock relative to you. Ambushing fighters is just too easy as you can come in from above or below your target, or from the side, and he won't know you're there even if he does make a sincere effort to watch for enemy fighters. It's even more of a problem with the capital ships, as they don't exactly turn on a dime.

Yes, the AA guns on top of the walkers in vanilla suck as anti infantry waepons. Same with the AA implacements.
