A few ideas:
Make it op, there aren't many OP factions servers.
Let people proceed ranks by their game experience (Say, if their faction has no members but them they're a Noob and if their faction has 100 + they're a F-Admin Master and for other players perhaps an admin/person with these abilities goes to their house and checks out their stuff and builds and decides whether or not they can go to the next level - F-Admin Masters should have this privilege) and let them get more commands per rank.
Add a roleplay section where there is constant regeneration?
Those are all my good ideas
