If a realm of 10 nobles and 4 regions has a "house of lords", is it discriminatory? If not, if that realm takes 5 more regions, is it then?
Honestly, I don't know how I feel about it. I don't think the former is bad, but should territorial expansion justify scrapping a political system that might have been working good for the realm? Obviously, excluding one or very few people from discussions for no reason isn't really a good thing, either.
