I still think that some form of government service record is also needed. Prove to the region at large that you are willing to put in the time and energy, and that being the delegate of the greatest region isnt just some conquest.
Ive found over the years that most of the best delegates we've had have been those who have no qualms about working their way up the ladder by holding an elected office before rising to the highest in-game position. Its those people who take the time to get to know the people who make up this region, and who work to make their mark BEFORE they run for delegate.
