The gunner of the Apache should be able to go into first person view to be able to repair the heli at the cost of not being able to fire the gun while in this view.

I feel this would be a nice balance because the gun is insanely broken and if a buddy is needed to repair the heli then this should be the alternative for the Apache.
Especially since every time my buddy and I get out to repair the chopper some little sh!t rams us and destroys the Apache so there's hardly any chances to repair it at all because it's either someone steals it, you get killed, or you get rammed by a teammate.

The gunner repairing adds 2 things.

#1: It would make it so that any class could pilot seeing as there's no reason to be an engineer as the pilot.

#2: It would be a much less lazy balance seeing as there is still ways to counter the Apache and might be more well-received seeing as repairs would force the gunner to stop firing and the pilot would have to temporarily exit the combat zone, in turn giving guys on the ground some much needed breathing room.

This adds a semblance of balance because it forces pilots to be a lot more careful and more cooperative with the gunners otherwise the chopper is going to go down.
It means no more billy b***** pilots and rather a proper collaborative effort.

Please take this into consideration.
