Bouncing from nation to nation as I and others do, I would like to suggest a Pirate option for those who wish to pursue only a career as a Pirate. Beyond the whole "person without a country" mystique it greatly hinders players who are Pirates. While the monetary discount is nice, at least a loose alliance of Pirates and the ability to hold a title gained via raiding over trading. While many players enjoy their current nations, being a Pirate should carry a little more benefit in my opinion. Quest and requirements are up to everyone else.
Pirate's Alliance
A chaotic and changing group of the most infamous Pirates in all Avonmora, this group acts as a nation but grants far less benefits, this is due to disorganization and common betrayal among Pirates. While nations enjoy many ranks and titles I would suggest 6 Pirate titles:
Landlubber
The newest and most ambitious among the Pirates. This would grant only the title itself and offer the protection of those who adhere to the Alliance's edicts.
Scalawag
The trained and newly successful among the Pirates. This would grant a trading bonus in Pirate controlled Ports
Seasoned Cur
A local name which traders avoid and port gossips repeat. This would a Repair and Trade bonus in Pirate controlled Ports
Dread Captain
Known in multiple port this person is spoken of in hushed tones, merchant hate them. This would provide a defensive bonus to Pirates in Pirate controlled Ports. It also would provide voting rights, these players would act as Dukes in relation to the current system.
Scoundrel King
Beloved by the masses, hunted by every nation, and the most dangerous person in Avonmora. This rank would be held by a single Pirate, effectively he is their King. It would provide access to a SOTL which allows for additional stacking of attack voodoo for its fleet (Hostile Natives, Fugitive from Justice, Bless, whatever is applicable).
Just an idea.
