You guys put far too much weight into the Story Group. They’re mainly there as advisors. The two that do the most heavy lifting are Pablo and Leland and they just ensure that whatever a project’s director/writer is doing is consistent with the established lore. And there they’re fairly powerless. See: the Starkiller’s carnage being seen from Takodana and Holdo’s last stand. There is no grand road map, they’re just doing things project to project.
I believe the heavy lifting depends on what kind of content it is (movie vs tv vs book, etc.). Also they’re not just advisors, they’re development executives.
