War of the Chosen is a great example of what a DOS2 Expansion pack should be. I know Larian doesn't like expansion packs, but it is worth considering it.
Yeah... Thanks for the plug that isn't descriptive, doesn't say why it is so good, and ignores the many shortcomings of the expansion.
Which you NEED to when the game in question is an entirely different genre.
Might as well go "Hey, Dark Souls is a popular game! you should be more like Dark Souls"
