An idea to be implemented into the official factions perks; Mining and salvage officials getting an additional, say... 0.5 modifier value on their primary mining drop. So, Niobium for IMG, Gold for Mollys, premium scrap for Junkers, etc...
And as for battleship bases, I'd reckon they should have about as much armor as a CAU 8 battleship- This might seem like overkill, but realize the battleship POB couldn't use nanos, or actually move around to dodge incoming fire.
Sucks to be a weight on the wrong side of the brilliance-insanity scale.
