You actually use growth curve to decide how you level? I just level based on who I will actually use O_o

For example, between yuri pirates and Marie Antoinette, pirates are more useful (because very little in this game has contradicted the "best defense is a good offense" adage yet), so even if they take longer to level I will get more benefit from leveling them to max than I would splitting XP or focusing on Marie.
