I don't think she's bad, as such, just... kind of plain. She doesn't have that much to do in the story; outside of her own story, which is just a glorified tutorial, you could remove her from the game and nothing about the main plot would change. So she just ends up not getting a whole lot of time to develop as a character, compared to the other lords. If she had featured more in the main story, and had more time to develop, I might have more reason to like her. Even considering her as just a regular minor character, her supports don't really reveal anything especially surprising or interesting about her, or anything that you might not have expected based on what you see of her during the story. Maybe saying I don't like her is overstating it, since she doesn't really do anything to make me dislike her; she just doesn't stand out to me that much, is all.
