I think you're being deliberately misleading. It's an upgrade to deluxe edition, which is a much better option than having to buy the entire game again just to get the stuff in the deluxe edition. And as far as deluxe editions go this is pretty mild considering the only in game stuff you seem to get are a unique dice skin, camp supplies and some potions, extra bard songs, extra collectible? and items referencing D:OS2.

It's not like it's the "From Ashes" DLC for Mass Effect 3. For those who don't know "From ashes" was a day 1 DLC for ME3 containing missions about the last surviving Prothean. Protheans being the most important race in the story and possibly even in the ME lore. And after the missions that last protean becomes one of your companions. For many it was a very important part of the lore being separated and sold as an extra purchase. I even remember the late great Totalbiscuit boycotting the entire game because of that DLC.

Technically that's an out-game purchase.

They do, but barely. It's just a couple of minor in game items/skins and some out of game music/art. Still leaps and bounds better than locking entire missions or characters behind deluxe edition nonsense.

What DLC?

Ah yes, but you see that is a macrotransaction.
