I would love to one day see an ocean world as populated as the land one. And have everything you can do on land, be doable on the Sea, Maybe even turn the desert like navigation-less sea area into a place filled with islands and towns, towns with Mobs and World Bosses. Giving you a reason to never leave the seas, if you're one who prefers the ocean life. Make Ships into homes, that you can decorate the inside of, since, that's what they basically where back in the pirate ages. Since you have and still do, most of the time, live in them for months/years. more islands or faster ship speeds to not make it not feel so dread, since that's where horses excel at when going from town to town, compared to ships going island to island. There's so much there and it would be nice, if the ocean became a lot less of a weekly vell visit. It's basically another world.
