ideas so far from there:
1) ruler assign region with no lord to existing duke (with no regions only? any duchy? click war between ruler and duke?)... i keep forgetting if ruler can create new duchy from town/cities with no lord.. if they can, then it's no different from dissolving old duchy, then create new duchy and sticking the duke there
Don't forget, rulers can no longer appoint lords. Period. Ever. So this would not just be dissolving old duchy, then creating a new duchy in that region and sticking the duke there. It would be stealing a region from an existing duchy without its Duke's consent.
