Pirates cannot die due to bombardment?
I think it may be a good idea, to upgrade the pirate bases so that they cannot be lost due to bombardment of superweapons, i.e. the nova's.
As it stands, in a game with mostly TEC, the pirates die out almost immediately - I'm sure they're supposed to be a factor in the game, not killable just by remote. If you want to end the reign of the pirates, you must attack them directly I say!
