Tbh that just sounds like the issue is not difficulty balancing but rather the overall gameplay design. If they can't make a proper 6dof space shooter then maybe they shouldn't have done it like that at all, and should have invested those resources elsewhere or on a different approach.
Having read this now about spaceships, and the other article about planetary exploration difficulty, just makes me wonder if anyone there even had any concrete vision for the game at all, or they really just had to compromise on every single part of it just to ship it? Cuz it definitely feels like a bland game deigned by a board and assembled from pieces of a dozen different studios that weren't allowed to communicate for a decade.
