The problem with the campaign strategy was simple: there was no strategy. One to one, any FS2 terran capship is more than a match for its shivan counterpart if they are fighting broadside (except possible cruisers; haven't tested Aeolus/Rakshasa and the Lilith is stupidly powerful for its size), but they are hopelessly outmatched from the front. The colossus is actually better armed than the Sathanas (if the firing delays were better matched), but all of its firepower is spread along parts of the ship where it is never used. Terran strategy should consist more of flanking manuvers to exploit the known shivan weaknesses rather than simply placng ships in their path to get destroyed. And one more question: why are the juggernauts faster than the smaller, less massive destroyers? Given that FS2 has no physics, there is no reason why a Hecate with all of its engine power could not at least properly match a clumsy and bulky sathanas in speed.
