Could they create even just one very, very expensive city where only the highest-level units from all castles, say level 7 and above, would live? This wouldn't change the balance because hiring all these units would still cost the same as in other castles, but they would all be gathered in one castle. Is this possible? And could they add an artifact that would prevent these creatures from fighting each other and causing a morale drop, and make this artifact very, very expensive and rare? Could something like this be implemented?
