A nation is purely for a title if you were to apply for the "Master Command" as I call it, basically an "addall" command that will add someone to every town in your nation, other than that, there is no use for a nation besides something for you to call all of your towns together.

 

I thought you could get a kickback on cheaper town to town portals within your nation? Did I not read that right?

 

you can get portals between two towns within your nation for cheaper than portals to spawn.
