I can not defend Bungie on everything, since they also did many bad things, but seriously, their effort for making the download files smaller by including what they can in the disc, and spreading the downloads to weeks to make sure people don't have to download a huge file at one time being taken this way by some people makes me mad. What people are glitching into are mostly unfinished areas. Some only have placeholder Dregs, some don't even have spawn triggers. Bungie has decided to include them in the game or in the updates, so that you can delve into the expansion content much quicker and don't have to wait a huge 5-10 GB download.
