A desire to achieve is not enough. Without actual achievement we cannot judge dedication. Finally, we come to an ability which may never be displayed prior to ascending the Baronial throne. When this ability has not been displayed, a Barony will need to judge potential and commitment to unify. This diversity is a strength when properly managed, but without management it can devolve into a lack of unity and even factionalization.
Strong factions are one of the primary reasons why some Baronies end up with weak leaders.
The strong leaders are in the factions and therefore unacceptable to every other faction. For truly great accomplishments a Barony will require all of its strength, the strength that comes from everyone pulling together. That is unity. Unity is not uniformity. In our Society achievement is a structure built on the foundation of diversity.
