Shortening the duration of an event but not reducing the grind (and arguably extending it with the lack of purchasable memoir upgrade mats) is insane. We basically need to compensate for 900+ naturally gaining stamina (assuming you're only using 240 of the total 480 potential stamina a day, otherwise it's closer to 1800+) we're losing out by the event time reduction alone, and we're more tied to the lottery for upgrades by relying on it for event memoirs on top of potential crystals for the event character. I think it's clear the event was never designed to be done on this short of a time period. I really hope not all the events will be like this, because this is a terribly incompetent way to quickly rollout a global version of a game, despite having (I believe) a solid core.
