My thoughts on the matter. yes, frigates ARE anti sup and anti air irl. however, they are also fast moving missle ships. perhaps instead of torpedos have foward firing missles, LIKE torpedos, but capital sized. low manuverability but heavy hitting, for anti caps, to prevent missle spamming. make them use cerb style power requirements and we have a good missle salvo unit that isnt overpowered. perhaps give it 6 cruiser guns, and light cruiser armor.
