All I know is the story keeps getting changed on the fly and it just a cheap uncreative way to extend game play. For example Dredgen Yor I believe in the original story was meant to be a warlock. There was a warlock walking around the dreadnaught in the live action prerelease for destiny vanilla. The same warlock (same appearance in gear at least) is depicted on every single thorn fragment card. Then destiny comes out all of the sudden there are cloaks and artifacts of Dredgen Yor that suggest he was a hunter. However recently a new bit of lore was added that would highly support him being Rezyl Azzir which is a titan. I believe the titan bit wasn't originally there in the first place and bungie did it to discredit the masses who all though he was a hunter or warlock. After all bungie prides themselves in discrediting stuff. Its not like any of the lore for roi was intended to exist in the first place as it wasn't a planned expansion or part of thier original story.
