Space Fleets:The Consortium space fleets aren't terribly overpowered despite their Aggressor capitol ships. The Aggressor's super cannon has the cooldown of a typical laser battery can can wipe out a hardpoint in one shot.
This is the one part i disagree with. Aggressors are taken apart quite easily, turn damn slow so just attack them from the side or send bombers for their big guns, those can be taken out quickly. But yeah if you can protect them they'll obliterate any capships.
The ones overpowered IMO are the vipers, they can rape just about any fighters and are great at protecting skiprays which has firepower that compares to defenders and b-wings. And you get em at tech 1 lol.
The other problem i see is that their fleets have tons of useful abilities, naturally they should have weaker units and have them compensate with their great abilities. However, most of their ships can stand toe-to-toe against the comparable ships of other factions, so those abilities make them op.
