To a player who wants to play SK as they could have before the advent of the mission system, many problems are posed. For example, if someone wanted to use the clockworks to level up gear and get crowns/materials, they would be prevented from doing so by the rule that restricts star level on equipment based on mission ranking. There is not even a clockworks substitute for missions. It would also be great if people could actually earn a profit by selling recipes as they once could, but the availability of most recipes in the Hall of Heroes prevents this.
