I went through this process years ago in 2019 because of how frustrated I was getting with their writing direction, and thinking about what could go differently.
Classic’s story was great in the senes that it offered us a really wide lens view of Azeroth, but the stories weren’t that deep due to a very shallow narrative direction over all (not a failure, just something they were still figuring out).
The big fix I added when I went back to write my A Proposed Revision 🖊 was to try and knit together some of those larger stories, and also expand it through the current expansions.
Odyn and Helya play a pretty big role throughout; I thought their influence was hugely underwhelming.
