XCOM 2 is such a good game that I feel strange doing ... It should be noted, though, that the game's marquee DLC, War of the Chosen (which is excellent, and definitely worth a buy) isn't similarly ...
One notable change with LWOTC 1.2.0 is that the mod now requires XCOM 2's Shen's Last Gift DLC, which awkwardly isn't available to buy standalone on the Steam store (you've got to get it in a bundle).
