The side to side (L1/R1) in the options menu was tough to navigate. Accessing the side to side with a highlighted/color visual marker would help out. Plus, it always seemed that when I did have to access the options menu, its was always to adjust the loadout or to find new missions/map. Have those be the first options when the option button is selected so the user doesnt have to scroll past the lesser used screens.
Also, invert camera controls for helos/drones.
