Yes. The Consortium Faction had overpowered the Empire and Alliance because those Keldabe Battleships(mass driver) and the Aggressor Battleships(megaweapon) damage your hardpoints directly. I think the worst fleet you might get will be a group of Aggressor Battleships.
Unless you try modding, when other newly designed ships come hyperspace into the game. That would be a different story

and you can even customise your units if you know how to.
