update
I made a new french territory: Champagne. Now France have 8 territories, but I can give 3 more: Toulouse (2) and Barcelona, because these are semi-indepedent vassal states in 1000. (in this case I make a 4 bonus of Leon, Castilla, Navarra, Aragon)But if I make this than 11 territories not will be too much for a single bonus?
Or should I make a smaller bonus for the french core and a bigger bonus for the empire with vassal states? (In this case Bretagne, Flanders, and maybe Normandy will be vassal too)
