Honestly, I think I'd add option B right away, as a passive feature.
"Every duchy that contains at least one city or stronghold increases the allowed distance from the capital before anarchists become an issue and increase the tax tolerance".
No need to build anything, just have it auto apply. It feels fundamentally wrong how the game discourages realms from having more than one duchy. And the newish size limit feels too small, there needs to be a way to increase it to what it used to be.
Even without applying all of this, what would be much easier to change is the current realm size penalty bonus into a duchy size bonus.
The more regions are part of the duchy, from a certain amount onward(like 4 or 5), the bigger the realm penalty.
Realms that ignore duchies and maintain a single large duchy get more penalized then realms with many smaller duchies.
This would already make dukes more important, increase their role and increase their numbers.
This wont effect the core of the game radically as the ideas suggested earlier.
Allthough i do really like the ideas of duchal capitals.
I do really like how this conversation has developed. I still think Dukes should be able to terminate their lords at will, but I really love this as well. I appreciate all of your thoughts/effort shared thus far!
