So I haven't played Stellaris in quite a while, and just jumped into this mod as the Galactic Empire, used a cheat mod to mess around and try to understand ships strengths and weaknesses but I can't really get a grasp on it. I had a 200k fleet lead by a level 8 Vader lose half its strength to an 90k space station.

Is it fair to say that fleet compostions should match accurately to lore? A tector/aggressor SD for capital ships, ISD1 and 2s for backbones, lancers for point defense and Victory 1 and 2s for support? Or is corvette spam still the accepted meta?
