How come the FOB's are not customizable? And the marines uniforms, type and weapon, it seems like a great idea as you rescue more marines and unlock FOB's one could add turrets, specialized and defense buildings (i.e. medical, barracks, weapon lockers, artillery,...). Custom the marines to different specializations (i.e. medic, heavy, light,, guard,...) and also be able to assign them different roles. Kinda like a fusion between halo wars and halo infinite. To be honest i expected something else from an open world Halo.
