Also, why does C'thonia even still exist. One city and two rural regions is just... painful.
I'm not sure how the tax rate works these days. In the old days, a small realm like that could drive an almost 25% taxrate (maximum at the time), while a realm with 3 duchies would have about 13%. In that way, the smaller ones could actually compete somewhat with larger realms.
Avamar and Rancagua hung on for a long time on EC despite being "just... painful"
Atleast in Avamar this was a major reason why.
Speaking of that, Is there any bonus these days so that small realms have a chance to challenge atleast medium realms? (except sea routes like Arcachon
)
