Arbitrary in the sense that an Astral can rearm Atropos and Reaper torpedoes on Tridents and Daggers, but not frigates hypothetically?
It's not even just torpedoes. It's bombs and harpoons too-- maybe you don't have a problem swatting away frigates in a capital ship, but what about lighter varieties of cruiser, or destroyers? Do you want to invalidate them too?
Flying a frigate is a very viable strategy, if the dozens of players running around in Tempests are any evidence. I don't see why you can't accept that maybe it's not good at every phase of combat, or every kind of combat. I fly a capital ship, and I spend most of the early phase flipping between combat and tactical views to manage the battle and not doing much else. Sometimes I don't even deploy with the first wave. Should capital ships get their speed raised to 150? I don't think so.
If all you want to do is make the Astral more viable, why not suggest an additional flight deck? Maybe an electromagnetic catapult to fling strike fighters on target faster? I honestly have never found it to be overly useless myself, so I don't really understand, but making a supercarrier cheapens at least two classes of ship and opens the door to a ridiculous outlet of firepower.
