Obviously on factor would be era: Because certain era's exist, you would have immediately different faction modifiers (proto Crusader, Warden and isolationist factions before The Wolf Dragoon compromise, Operation: Revival's Crusader and Warden factions, the two resulting but different factions post Wars of Reeving). Obviously modifiers for specific Clans in regards to other Clans, Rank, Blood Named or not, Ristar or not, Dezgra or not, True borne or Free Borne... :D
