Now, there is a very important part of writing big story, which Thomas doesn't follow (see also Kree-Skrull War) and that's planning it out before writing. The structure ended up absolute mess. For some reason he decided to retcon Sersi's powers to be illusions.
But that's just a part of it. While Eternals required tremendous amount of explaining to fit into Marvel, Thomas decided that if he is cleaning up continuity he will also clean up fuckton of things from Thor. Thus he introduced Ragnarok circles, explained why there was no female goddesses for long time in Thor comics.
Combined with what I mentioned about lack of planning, this was basically a long ride of infodumping and retcons. And then Gru and Macchio were brought in, seemingly to finally end this.
