I feel like the loss of the BoC has really impacted the narrative this edition- The setup for something as good as the Broken Realms series exists, but it feels like they didn't commit to it because the plotline needed to set it up was scrapped. You can see this because I'm pretty sure every codex covers how the faction handles Incarnates, but the Incarnates themselves weren't ever used as a plot point outside of Thondia. (Speculation) This was probably due to both leading up to a BoC refresh and a different story than the Dawnbringer Crusades that probably focused more on Kragnos, . I think the only major through lines I can think of for the crusades that are actually starting to pay off are the CoS, FEC, Skaven, S2D, and the OBR of all people (Specifically the "Mysterious Hooded Speaker of Nagash's will" is literally Arkhan, the OBR battletome says that this is just what he's doing currently).
It feels weird, I think is the main point of all of this.
