Story-wise I can easily think of a "power-reset" mechanism. If they decided that "time goes differently in Shadowlands" and we returned to Azeroth where 30 years passed, with our powers drained as a cost of defeating the Jailer, that would be a perfect opportunity to reshape the narrative of WoW's story.
Going into cosmic stuff is wrong as it simply removes the boundries intrinsic to any fantasy universe. As long as you believe the Titans are the greatest force in the universe - some sort of "the Makers" - the story is maintainable and sustainable. The moment you make a correction / retcon, create a narrative of powers X that are greater than Titans, then powers Y that are greater than X and so on, there is nothing to stop you in continuing that - I belive you can get my point.
So compare that to, idk, Tolkiens works. He created Silmarillion - a blueprint for all his work. There's a story of a gensis for this universe, he describes powers ruling the world and that's it. From there, you can make anything work as long as it's inside these boundries he created himself. In contrast to WoW, due to many retcons to the story, these boundries have been removed not once (via Chronicles), but now twice (via Shadowlands broker's POV). That lack of story / universe integrity cannot lead to cohesive storytelling, let alone a great experience.
They pretty much fcked it up time-travelling and the merging of parallel and actual realities.
Parallel Gul'dan has been sent to
our world, which cause
a lot of story problems and paradoxes. And from there, they picked up with Argus and cosmic stuff, Void Lords and so on. After all, Titans were not so powerful.
I believe is what people truly desire are simple, down-to-earth stories of local communities. You can relate to these stories and these are inherently associated with Warcraft genre.
But I'm open to be wrong
