Separate levels that your faction can upgrade to that cost both money and respect to "buy," and they give certain happiness levels (slightly lower than PI for max), they can be upgraded like actual properties, and everyone who chooses to can use the same Faction House. It incentivizes factions at a lower level as well, as I know many are afraid of joining Factions for the aspect of being constantly hosp'd during wars and disputes. I feel this would bring quite a bit of depth to the Faction and help with training for those higher level Factions.
