If you find it to be a lot you can always prioritize. Mr.Divine Dungeon is only important if you want to get + units and some boss units in the area series quests are only okay at best. Of course that is all moot if you are an avid unit collector ^^; Holsten should be up on the 3rd and 4th of this month~

Actually it might not be as difficult to acquire them all as your stamina bar will automatically refill at midnight (JST) for a couple days.
