its an idea that basically makes all pvpers have to be in factions and it's a bad idea at that.
The goal should be to provide meaningful benefits from factions. on the old forums it was brought up that control of cities should provide substantially greater control in general.
The guards should be highly customizable so that insta whack guards in faction cities go bye-bye and are replaced by faction guards who can decide whether blues, reds or grays are enemies of the city based on the sheriffs decisions. The sheriffs could also set guards to attack any group they desired(possibly making all members not in their faction KoS by the faction guards). The finance ministers should have full customizable control on pricing of all vendors in the city to faction, enemy factions, blues, reds, grays. They could also place levies for opening the bank, if enemies choose to bank there.
Factioners should also be able to use large quantities of silver to produce invasions of non faction cities with their aligned creatures. Faction aligned creatures should be expanded to include more creatures.
this is what I remember of the thread, it was a pretty long running and widely supported idea, I'm sure some other folks could elaborate.
