I am a king and I just had a vassal turn himself into a duke. But I don't want him to be a duke, I liked him as a count. Now I can do various things to revoke his duke title, but then I get it and will have too many duke titles. I could give it away to someone more loyal but I'd rather just get rid of the title entirely. Is there a way to do this? And if not, what is the penalty for having too many myself? Is that workable?
