1 i would like more players on a server the world is so empty with only skeletons and a few NPCs who sell stuff, and not much stuff to that.
If you add more players the world might feel cramped so maybe some extra sea between islands, and to avoid slow sailing just bump the sailing speeds up too. This will allow for more players but still open areas, i just wish i could ever find a sea battle of 2 armadas clashing 10 galleons charging into an epic battle.
Finally in my empty worlds i question if it is empty in fact. I would like a menu with a list of ships, (customize our ships name) and the people onboard.
