I have no particular thoughts one way or the other about the event itself.
I just want to take a moment to articulate that Wax Tree is the worst. The worst. The artist responsible for this abomination, and whoever else on the FKG team in Japan who thought she was a remotely decent idea, should immediately be fired, shunned and exiled from contemporary society. I've found a few of the loli designs mildly distasteful in the past but none of the other designs have led me to recoil in horror the same way Wax Tree has. Her very existence in this game is an affront to civilization, and if I have the misfortune of ever acquiring her in a gacha roll I am immediately ridding myself of her and scrubbing my hands clean for thirty minutes to cleanse myself of the horror.
...Fullmoon Maple's pretty cool, though. It's rare that the best designed character in a given update is the one you get for free with the event.
