The Faction-indie IDs are important to learn how the faction works, if there is one. If not, people can create a new faction based on that ID. It's really important we have them.
However, the OC indie ID is ridiculously overpowered in terms of ZoI and shipclass permissions, compared with other faction indie IDs. That, and the fact the Outcast playerbase couldn't be more open for everyone and their mother's roleplay goals, as it's basically the better Pirate ID. I'd split the Outcast ID into Maltese ID and Outcast ID, to be honest, as some OC roleplay has literally nothing to do with Malta and maltese lore.
