As an example, the Kzinti FKX is rated at 130 BPV.
It has;
2 disruptors
6 phasers
4 drone racks (2xGX and 2xCX)
1 shuttle
22 power
3 batteries
9 total hull
22 #1 shield
The Hydran LNX is rated at 116 BPV.
4 fusions
6 phasers
2 gatlings
28 power
13 hull
3 batteries
1 shuttle
4 stinger X fighters
32 #1 shield
On the surface at least, it would appear that the Hydran destroyer is quite a bit better than the Kzinti frigate, yet the frigate is 14 points higher.
What am I missing?
Thank you
