To advances, you are almost forced to make crafts leves, if you want to craft your character. There is a reminder of the love of Square Enix mini-games in the Final Fantasy series, but guildleves seem to be an important source to advance your character and for the moment. Considering the awards, the cool down is too long. There really is no option to abandon levees is hot, unless you want to start the cool down of 48 hours. So if you happen to be disconnected from the game (or forced to disconnect because of a bug), you will now have to wait 48 hours.
