Yeah, we don't know exactly what they will do here: done recall the last time a D&D book even had an Index, though?Not necessarily. An index isn't just rules. It also is a reference for key topics, terms, and etc.
If the book is able to provide the function of an index, cool; but the '14 versions struggled with that, so I'm not exactly enthusiastic about the idea of completely removing an index.
