It's a glorified glossary which sometimes only came in a strategy guide or a bestiary from the main menu. The fact that they include dialogue of their handlers or possible origin is for our benefit. There is much to come and there was exotic armor that referred to TDB that was out previously to its release. No people read into and claim cut content and lack of story but if you read my previous post we are the story. There have been few things to happen since the collapse and we have heard about them in game. Now Bungie probably feels they never should have given us that because what seemed like a good idea was lost like many others to the trolls that are sad pathetic people who can only see the negative and it blocks anything positive from giving them satisfaction.
