Burning Shores is a solid DLC. The new area is a decent size, the storyline is nice, Bilegut is cool, and the final boss is incredibly cool (even if hard makes it a bit more frustrating than I think it was supposed to be).

I just wish the new area was more "dense" in collectibles - it's not inherently a problem, but several areas have literally nothing special going on in them aside from your random junk collectibles you probably have full bags of. There's also no map icon for Aerial Capture missions or the Delver's Trinkets - while I think it's a neat idea, it boils down to having to constantly spam your focus while flying or moving around to make sure you aren't missing one in an area (and even then you need to be pretty close for either of them to show up as far as I'm aware).
