I would never miss this because when playing Ragnarok Online, everyone would always be farming the same exact area and it was almost impossible to fight a boss because there'd always be people camping it. So no, while open world may seem like a fun thing, in the end, it becomes frustrating for players who only have a few hours to login per day and don't have time to camp out a boss or a spawn. For people who love those kinds of things, there are FATES.
