I found myself asking this a lot during BFA. The entire expansion feels aimless.
It was advertised as the faction war expansion - despite finding the war rather tired by that point, I was open to seeing them really focus in on it, maybe add some interest. Even though I felt the world tree thing was a little too on the nose, it was fairly interesting to play through!
Come BFA’s actual release, and the war is immediately sidelined. Save for a few, clumsily written questlines, it may as well not exist. The only thing to even remind you that narrative is still there, is a ‘war campaign’ - the rest of the world seems to chug along without a care.
So it felt extremely odd to be told, by the end of it all, that this war was important enough to be the fourth war. It barely felt like a war at all. And that’s not even getting into the ‘breaking the cycle’ junk.
