My thoughts about this

About the old witch I strongly disagree with saying that people won't connect with her. If it matters I have read all of the Discworld novels and must say that the ones about The Witches are my favourite. I think if Rioters had some free time they should consider searching for inspiration in the following books: Equal Rites, Wyrd Sisters, Witches Abroad, Lords and Ladies, Maskerade, Carpe Jugulum
