I think it's kind of annoying Gage's story requires you to get max affinity and has no quest behind it because it's a very sympathetic and understandable set of reasons to be a Raider. I also liked the depiction of the Raiders of Libertalia and their motivations.
Ill grant you that Gage was interesting as was others, like Daisy and Mason. But it's not enough to convince me that this dlc is good. Theres just so little content that isn't radiant. Exposition is neat and all but how about you try to tell your character's story through actual quest content that has had some effort put into it? I dont think thats asking too much.
