I think that the political story of High Isle suffers from the fact ESO just doesn't have the budget to tell a political story at the scale at which events are occurring.
If you had the budget for it High Isle could have let the player choose to join the Order, choose to push for peace, or choose to push for the war to continue.
You could have met people from your faction that would have pushed each point of view.
Then, after your made your choice, you could deal with the repercussions.
Obviously, ZOS doesn't have the resources to spin the story off into all of those different directions.
I know y'all said this wasn't gonna be a cult story but these guys just don't have a good political plan. It'd make more sense if they were doing what they're doing as an act of worship to the Daedric Prince of revolution and change. Much more than the Waking Flame. High Isle just isn't a political story in the way Orsinium was. The order is just a glorified cult targeting political people and it's honestly quite a shame. Because as a result they're not compelling.
Honestly they didn't do Dagon dirty. He's always been big on destruction. The Waking Flames leader just believes that Magnus will remake the world after Dagon destroys it. Destruction is a big thing for Dagon to the very point I wonder that if revolution and change is something mortals falsely attribute to him as it's really just an aftermath of the destruction he causes. Dagons realm is literally a destructive hellscape that goes back to TES4 and the Daedric realms are meant to reflect the Princes if I recall.
Just because a group wants change doesn't mean it should be a Daedric Cult. Making things a Daedric Cult because it "fits" doesn't help the setting as you'll end up the with issues Nibenese Cults have where anything that Isn't Daedric is barely a cult and only exists for one thing (rip Ancestor Moth).
Also this year is toning down on the Daedric stuff because they drown everything out especially after we just had a year with Dagon as the focus.
We also do not have the full story nor do we know the actual goal and intentions of the Ascendant Lord which is why one should wait for Q4 before one can critique their writing. Like do they want to get rid of the current rulers to put themselves on the Throne?
If Blackwood did anything dirty it was the Imperials who are always done dirty because literally everything of theirs is never represented properly.
