Title: Allow Dukes to Secede a multiple city duchy that includes capital
Summary: The new Duke/Margrave separation mechanic has created a new situation of judging secession mechanics. Under this mechanic dukes can be liege over multiple cities making the restriction on duchy secession an outdated mechanic. Just because one of the multiple cities a Duke controls is the capital shouldn't stop him from seceding if he meets all other requirements.
Details:
First let me list the complete set of current restrictions upon a seceding duchy.
You must be Duke.
Your Duchy must contain at least one city.
Your Duchy cannot contain all the cities in the realm.
Your Duchy cannot contain the realm's capital.
You must be in the city (within your Duchy) that you wish to become the new capital of your realm.
This city must not have high independence/low control.
You must have been in both your duchy and realm for at least 2 weeks.
You must have at least 6 hours available.
You cannot already be the ruler of your realm.
You cannot be in an NPC realm (pretty much moot nowadays, save for bugs).
You cannot have a family member who is already a ruler on the continent.
There is also a difference between a Duchy containing the capital being able to secede and change allegiance:
Duchies containing the capital of the realm cannot secede. They can, however, switch allegiances. To even begin considering either of these two options there must be another duchy containing a city.
I propose making the simple change of allowing Duchies that hold multiple cities to be able to secede their duchy even if one of their cities is the current capital of their realm and ALL other current requirements are made.
Benefits: This change will eliminate the current dichotomy in addressing duchies that contain a capital of a realm. Why does it make sense that one can change allegiance while Duke over the capital region, but they can't secede if they are duke over the capital region?
Two arguments I presented in the helpline thread:
1. It makes sense to me that a Duke can't secede if his ONLY city is the capital of the realm. However, if he chooses to secede and create a new realm while having more than one city, and he makes the capital of the new realm a different capital than the old one you have a completely different set of circumstances than ever seen before.
2. I guess I'm confused what is trying to be restricted here. Every single other restriction I can think of a reason for it to be in place, but this one baffles me. What is different about a Duke seceding a three city duchy(in a 4 city or more realm) and a duke transferring the allegiance of his three city duchy to another realm, (perhaps a one city realm).
Exploits: None that I can think of. Most exploits are taken care of in the other requirements.
