Okay Rare, i love the game but like most i want more depth, and you guys seem to only know how to make it wider, so i'm here to help you. You should add a Royal Navy section of the map on the left side, an expansion of the map like you did for the devils roar. this area could include the following suggestions;
2 new navy outpost (including adding 2 more possible ships on a server)
A navy fort, so it could be like skeleton forts but with navy guys, and more fortified and organized, so it would be difficult to take it.
and most importantly it would be awesome if say, a player ship attacked another player ship in that section of the map, and then the ship that attacked gets attacked by a navy ship or two. So this area could be a little safer than just the open seas for people that don't want to have to fight all the time, because the navy ships would help stop people from attacking each other.
You could expand on this by making it possible to trade with the navy ships which could give you reputation with them.
you could even add one or two navy ships that go around the entire map that you could trade or fight with, and or you could make the navy ship that's going around the map an event style thing like the skeleton ships in where you go to fight it and it's like a cargo load that's really hard to fight, double decker guns/bailing water, and so on.
I think you guys at Rare do a great job and i really hope you take this idea into consideration, i think people would have a blast with this huge change to the would. I love playing as a pirate so much and everything that goes with it, i just feel a little like if everyone is a pirate, no one is.
