I keep coming across the same issue when converting ships from other systems or settings into Starmada, and that is of ships that can carry a given number of fighters but those can be of different types.

For example, you could have a setting with multi-role fighter X (50 capacity), scout fighter Y (45), strike fighter Z (55).  A ship could carry, say, any 3 flights so I would design it with Carrier (165) but that would then encourage the use of nothing but the strike fighter otherwise you are wasting Carrier space you have paid for in both space and CR.

It gets worse if you have a bigger carrier - one that could carry 10 flights would need Carrier (550) but that would allow it to carry 11 flights of fighter X which it can't do "historically".

Any suggestions?
