We can adjust the idea proposed here.
Remove the size limit on merge. Even devs get confused with the number of nobles they set. Better remove the restriction so nobody has to remember the arbitrary number. Plus when the realms become too populated and too large to the point people can't stand each other, they can simply form a new realm since they will have more than enough nobles to do so.
As for disabling the option to join realms with under 10 nobles, we can also disable the option to join realms with more than 40 nobles so realms in between can get the full benefit of new players.
