The solution is actually just removing Nomads a playable faction because they're absolutely awful and have been for the past 8 years if not more. Current iterations of Nomad factions provide you a grandiose choice of picking between circlejerkers and transport hunters.
Indies on their own aren't bad, but the faction's way too restricted to keep indies around and expect them to stay active (as is evidenced by the fact Nomad indies have been largely gone since 2021).
