Past Level 50 Suggestion

Would there be any possibility of creating an island that would need to be conquered and then managed for players past level 50. This would involve creating forts (bases of operation) and then as an area is taken over another fort must be created and supplied with enough troops to keep it viable to protect the area.

Settlers and troops would have to be ferried with a general and as an area was conquered the economy in that area (fields, mines etc.) become a part fo the economy of the island. If the conquering general failed to maintain a strong enough presence the areas could be retaken by insurgents

I would like it if this area was pvp enabled. (video game design student here) I think it would be a good idea to have a colony based end game where players build unto guild cities in a pvp enabled land.

As someone who is professionally reviewing this game, I think it could use something like this.
