@Bulldog. Indeed, I've often found that subtle changes are usually effective, after all we don't want to detract from playing as indepedent but rather give people incentives to form or join factions and aim for officialdom.
@FluffReborn It's that responsibility and self-regulating behaviour that I believe make official factions a cornerstone of Disco and help create a sense of community within the game, but as Timmy said the bonuses given to those factions are only used by the leadership and offer little to the members.
