Hey i keep getting my home nation on my npc list. Can you fix that please ?

You are off topic so I splitted this into a new topic where it belongs.

There is nothing wrong in getting your home nation at the NPC list.
If you follow the "How Patrol works" link at the right of the Plunder page, you will get to this page:
http://s2.piratesglory.com/?page=help&action=patrol

Where it reads:

Help wrote:4.Countries of NPCs DO PLAY A ROLE as NORMAL. For example, you may want to avoid attacking your nation fleets if you do not want to be banished (or target them if you want to become a pirate).
5.Only Top20 Nations are taken into consideration when generating NPC fleets. Chances are equal.

Recently a new player asked me about how strong npcs are according to how many ships you got? where can someone see that? every how many ships does npcs become stronger?

While we provide any piece of info you might ask for PvP side of the game, we are not doing the same for the PvE (Player vs Environment) aspect of the game.

How exactly NPC strength is determined, is one of the chapters where I do not recall any insight given from us, including the ship number you are mentioning.

Simply said, that's up to every player to discover and utilize.

I see. Thanks a lot
