Most everyone I see post about wanting to quit the game is due to not enough opportunities for individual fame and fortune in one way or another. A lot of people believe going pirate solves this. But if you are on PVP Global the pirates are not that option, as there are so many of them it is barely different than being GB.
With that in mind several people just quit the game and come back on the next major patch to quit again. There are other options, such as going to a small nation, like on Global the Spanish, Dutch, and the totally not fascist regime "SS" of sweden. These nations need players, and are more than willing to help others out to achieve ranks and fortune. Save for maybe sweden.
Short: Try a small nation before quitting. Help other nations grow and become powerful, and in doing so become rich and powerful.
