So I was playing along as advent and I noticed something: Final Judgement level 2 has a shorter range than level 1, so short that it can't hit the planet that it's attacking unless it was originally built right beside it (not that anyone would use a starbase offensively... although it is fun to build a couple beside an ally's planets and wait for it to go to war...)
So as it stands, in order to attack a planet one would need Meteor Control level 1, and level 2 would do nothing. (Goes from range of 10-15K to about 100).
Just thought I'd mention this, haven't seen any threads on this. Dunno if this is really an issue though
