Reduce Settlement Trading Value
Do you have no self control?
or
Do you want to use the settlement trading mechanic without feeling like you are cheesing the game?
The picture is an example of a level 1 Grunburg with a single barracks, we can all agree that it makes no sense that at turn 2 you could vassalise or MA anyone in the game like this.
All this mod does is reducing the value buildings like barracks add to the value of the settlement to a reasonable amount
You still get bonuses for all the other things for example, the other side owning a partial amount of the province.
So a level 5 settlement will trade for a lot more then a level 1. But a single settlement should not be enough anymore to convince even you worst enemies to be your vassal
