Could you please explain the use cases of such a system a bit further? I am not strictly against it, but I am afraid, that there will be not a lot of usage for it. Should it be close to M-OEE8? Does it have to be in 0.0? Does it need a Keepstar or would a smaller structure (like a faction Fortizar) also be sufficient?
Regarding the separate combat system for sub-capitals (as we had with PVH8-0): I’ve seen nearly no activity in this system and there was also very little support for it in the discussion thread about the rule changes, so I left it out for now - but this would also be quite easy to add again (if there are any good arguments for it).
