all items were removed from the legacy quests as far as i can tell. some of them are probably a bug, but the gear is probably intentional. you used to get 3 exotics throughout the red war campaign--those are gone and what i think were intentionally removed. you also used to get a cache detector shell for each area that is exclusive to the campaign and those are removed. lastly you're also supposed to get a class emblem which you no longer get. the encounters where you normally would have received those items are completely gone--both item and dialogue. leads to some slightly choppy story transitions in addition to many missing collection items. the only dialogues that are in-tact are the ones that used to reward an exotic, which is why i think removing the exotics was intentional since that's the only one that was done properly. no idea how much is intentional or bug since i haven't seen bungie respond to any of these nor has anything been in any patch notes as far as i know.
