I'm not sure about bonuse.
I used formula
Bonus = ((Borders outside bonus/3) + territory in bonus)/2
I add 1 in "Center" bonus as a strategic point.
Base = 5
Crossroad = 3
Center = 6
What do you say if i change it into:
Base = 4
Crossroad = 2
Center = 5
I also though about higher bonuses but without any idea.
