Feldon Game Update 56 will contain minor tweaks to Betrayal and changing one’s Citizenship.
Changing citizenship is being streamlined, as some cities require more busywork from players than others to switch between cities of the same alignment. Contacting one of the new Ambassadors in each city is your first step.
No changes to the actual betrayal quests are being made (changing alignment ) are being as far as we can tell, but an Ambassador NPC is being added in every city who must be contacted prior to deliberating the Betrayal process. You can read more about these Betrayal changes which have been extensively documented by Domino at the EQ2 Forums.
These changes are likely an additional safeguard to reduce the number of customer service tickets resulting from accidental betrayal.
