campaign balance

To balance ships for features they don't have, I'd (roughly) recalc for the
ship sans the useless feature.

For example, in convoy attack or planetary landing scenarios where the ships
are pretty much defenseless (a couple of PDS), I ignore the cost of the
transports when determining balance.

That seems to work reasonably well. Just make sure the attributes you are
referring to ARE actually useless.:)

air shows up... it can be turned to anti infantry role!>
