I am having a big think over the following: I have some 3 enemy bases on the map (2 merc and 1 star gods). I tried them when they appeared and was defeated badly. Now, after some time i feel I could maybe wreck a merc base now, but it would still be a very bloody on my part (loosing some high-level gals and power armour I made from downed enemy over the months), and with little useful loot to show for it (Gauss guns are coded, and I already have lots of cash).
Also generate enough infamy to tank the infamy penalty for enemy bases.
So my question is are there any other problems from leaving enemy bases alone, that would warrant the high losses in manpower and irreplaceable materials?
