NSFW Acc: 
Blizzard: *releases a book, because more ways to enjoy a story is fun and expands on lore that gameplay won't always allow for* People: H O W D A R E Y O U I get it, playing through certain story beats would be awesome. It ain't always gonna be possible. Books are fun.
I am ok with it as long as the game explains enough of that book story as needed to make sense by itself (the game itself should give enough context for the main story of the playable content)
