They're not a requirement or fit for everyone by any means. I think the work's scope is a big factor, but preference can overrule that.I can see YA / kids books doing it, but I don't write that, and like to think my reader has paid attention. I wouldn't give a list saying - 'here's all the characters you will meet', at the start if you know what I mean?
I just checked because I couldn't recall: Dan Abnett's Horus Heresy Book 1 (yikes, of 53) has a dramatis personae in the front too.
