Another example is Old School Runescape, who reverted back to an earlier save and has now diverged as an entirely separate game running with older systems as they lost a ton of players with their "Evolution of Combat" update. While nostalgia is definitely a powerful tool, I agree with the previous commenter that the original WoW was a very different game than the modern version and it seems like that is one of the core aspects of what people desired.
