Sorry to resurrect such an old thread but I just tried out Midnight's Assimilators...
I only got about 2.2 cred/FP ratio...
Is that because I didn't max out the swarm bonus??? I only tried it with 10 ships in a fleet...
You may not of picked the right design there are quite a few copies. Also stats increased by a swarm mod does not effect a ships power so no you don't need to max the swarm mod. If you have a gold account I would look up MegaBooster it is quite a good pship. It's the one that costs 78.600 it should give you a 1.1329321465893120968613743648878:1 Credit:FP ratio if you have a golld account.
