[Baron Munchausen]

Like others have said here, keep your ship types 'pure'. All seekers or all DF, and a few PDC in each ship. Give the seeker ships "maximum weapons range" strategy and give the DF ships something like "Optimum Weapons Range" or maybe "Short Weapons Range" or "Point Blank" if they are shorter-ranged powerful weapons like Ripper Beams or the Graviton Hellbore. Carriers should have 'Don't Get Hurt' as their strategy and no weapons except some PDC. Make the carrier a big launcher with as many cargo and fighter bays as possible and let the fighters engage the enemy. It's good to combine many different types, just keep them fleeted into distinct Groups with the proper strategies.
