DCC Rewrite

A professor once told me "You will always want to edit or rewrite your stories, even after it hits the bestseller list."

The tone has shifted quite a bit from book 1 to 7, I wonder what things would be reworked if Matt had the opportunity to rewrite the entire series, knowing what he knows now.

Which plot points would be moved, added or even destroyed? Which characters would be removed entirely? If Pater Coal's scene became it's own novel...

What things would you like to see changed, expanded on, or even removed?
