The MainCamera takes its values - rotation, position, and FOV - from the GameCamera it's currenty attached to, i.e. the one set by the Camera: Switch Action, or the Scene Manager's Default Camera field.
If you're using First Person, however, then the MainCamera attaches itself to the First Person Camera that's inside your Player's hierarchy.
