Some newbie thoughts...

Fighters can be extremely powerful, especially when mixed well, think of them as infantry in medieval combat, with your ships being horsemen or chariots, it takes a good mix to really work things right. Heavilly armored Phalanx defend my Groups from point defense without really doing much damage, faster moving pikemen line up in squares to attack ships and planets under cover of Archers using point defense weapons of their own, and of course my ships play the part of the assyrians at babylon, CHARGE!!! Swerve!!!! Fire!!! lol

These kind of tactics are especially good if you combine them with naval tactics, troops are just like ancient pirates, grapple the planet, fire off a few bombs if you have time, slaughter the defenders, and take the loot, hardest part is (and always was) getting a foothold on the enemy vessle, in this case a planet.
