I hope they will and they can in future release. I mean just put a limit where players can go in a sea. Maybe hidden underwater dungeons that you have to dive and you need special rare loot from a monster or quest that lets you dive for longer to reach those deep sea caves/ruins or sail to a new continent or a new island. Something like that. It would be so cool. It doesnt mean a sea battle. Something as basic as that can lure in players and increase the diversity of the game.
