Any specials that can be used for army building are always welcome, I think each batch should always have at least one of those.
When it comes to medieval heralrdy, they somehow insist on always adding more kinds. While the creativity is to be admired, I doubt many would mind old heralrdry being recycled, most would welcome it. Heralrdry is only one part of the character after all, they can do new things with the clothes, hair, weapons, etc.
