We could always use the power calculation formula from SO Elite, it was designed as an improved fleet power formula.
But that would eliminate most of the powership tactics but it would make the top 10 fleet power more ship cost / asset related... could try for a round I guess, if enough players want it
- ship power formula:
accuracyPercent = (1+accuracy*9)/4; // max accuracy percent is 1
fleetPower = (fleetCost/2 + attack*accuracyPercent + defence*3 + hitpoints)/100 + absorb*500;
A much easier solution would be to make all ship that would be captured in boarding explode if DDAY is active, or when the attack power limitations are removed for DDAY members on Warning day. Would make sense, if you can attack someone 10000x your power, that you can't capture that many ships with your tiny fleet.
