Batman Arkham Knight Patch Review: Is It Worth It?
DLC's not even relevant to this article. There's a difference between Day 1 DLC on the disc and Day 1 DLC that needs to be downloaded, it sounds like you're confusing the two. Also you're not being a guinea pig, just download the patch. If anyone should complain it should be those who don't have stable connections like @brendon987 stated. I have a metered internet so I can't download this patch until midnight without using my data limit, and I'm not really complaining.
