Please make them rather Capital than Support. Capitals can be protected by Escort ships. Support ships do not go to the front line. So they do not participate at a lot of fights (their weapons and upgrades of them do not matter).
It's actually not set, there is logic that determines the ships role based on the upgrades, defenses, components, etc that it has. I actually modified the Commander component in both the Threat and Value dimensions, but not in the fortitude dimension. So it will be a lot more careful with them in battle.
If they fall into the Capital or Support roles depends on their other components (notably carriers). And Small ships (the tier 1 command ships cant be capital ships, so they are more likely to go to escort).
Since it is programmatic it may not be perfect for every ship. But it will do a much better job of evaluating their roles in battle.
