I understand that most of the community that has been preparing for this event is expecting to unlock missingno on day 1, or at least hoping to. I would remind you that a SEVEN day event with SEVEN stages would be perfect for allowing exactly one stage clear per day.
Moreover, this would or could drag the event out for multiple days, instead of just a whirlwind or stages, droids, credits, and ability mats, followed by "see my 7* <insert name here>" and "nerf <name>!!!!!!111oneone". Which buys CG the most valued thing, more time before players have exhausted all content (if only for a week). Then again, I personally hope it's all doable on day one, sitting on gear and mats sucks.
