As discussed, too many of the major reveals and plot strands are baked into many years of buildup regarding the Ascians and the Empire, Hydaelyn, the world state, etc... divorced from that, the major reveals wouldn't quite land.
That said, the adventure itself is quite enjoyable and a very strong expansion...to an extent. I still preferred Heavensward overall myself, but this comes close. The zones are some of the best in the game, but the dungeons were...a bit lacking comparatively. A lot to like for sure though, but it is very much a strong chapter in a long running narrative, not something I could at all recommend on its own.
