Look back to old Warcraft games and honestly, the series has always been a retcon city with bare bones story and built on top of parody. Every sequal was loaded with retcons to the prior game. The stories themselves were often if not always parodies of existing fantasy stories and tropes. It was always silly and campy with the artwork being made by heavy metal band cover artists. Even the most celebrated story: Arthas, is just a fairly bog standard fallen prince trope that you can find in dozens of campy fantasy novels. Their most original idea was likely the noble savage Orc but even that was just taking the existing noble savage trope and slapping it on a none-human. The original Warcraft team were all fantasy nerds and its what they did. Warcraft is essentially the "Police Squad" of video games.
And it was great.
Things didn't start falling apart till the devs started taking things too serious. I'm not saying they shouldn't try for consistency, but the heaviest retcons always come from them trying to undue their over the top roots in some way. I'm not saying they can't be serious, but they've been leaning into it far to much and ignoring that you cant keep doing that with an setting with such an exaggerated, everything (art style especcially). They often seem to be embarresed about how corny the lore is and wanting to make it "super srs" which just, doesnt work. Its why the Zovaal thing just ended with everyone pointing and laughing.
