Like I said Ein, my issue with her is her treatment of Noire, which I agree with Strunk in that meeting Noire would have probably changed her to become a better mother in the future, as she goes from "Oooh, I'm going to teach my daughter to be a great sorceress!" to "No, this isn't what future me must have wanted. I loved her, so I didn't want her to become like me."
Her support with Nono is downright adorable, and many others, again, I quite like or have no problem with. Ultimately, it's just her treatment of Noire that makes me dislike her.
