Wanna change nation in FFXI? Is worth changing nation?

  Wanna change nation in FFXI? Is worth changing nation? One of my friends said to me: "I'm on Asura Server, I am in Bastok Nation which is NEVER first sell FFXI Gil and almost always third. I think bastok is okay, but the surrounding area is duller than a stump. I have my ring from them so that was the only benefit. Now is it worth it to change nations? I just hit rank 5. I have a fair bit of CP(i think you lose them when you nation change correct?). But i am considering moving to sandy because the city is better, surrounding area is better and i have a much much better ability of doing the outpost supply quests when my nation actually controls more than S/N gusta and the Valkurm Dunes area."
