To be fair, she was kinda humourless in Mask of Light. I just hope that's what they're going for here, and not "lololol she tells bad jokes! laugh children, please!" Also, I don't think anyone was reading any gender stereotypes from this, given that all the characters have flaws just as- if not more- stupid. If she were the only one with a weird character flaw, THAT might, might be gender stereotyping, but here, you're basically saying that women have basically been stereotyped with every single character flaw in existence at some point. While that is closer to the truth than I would like, I doubt anyone saw anything gender based in this characterisation.
