You're right that it didn't achieve the improvements that were hoped for, but it was a success in the sense that FANDOM gained insights about what didn't work and what would be a better way to improve the editing experience, hence the coming mediawiki upgrade. Even if the hypothesis is proven wrong, that's still an important lesson learned.

It isn't clear that the reasons for upgrading the MediaWiki engine had anything specifically to do with what was learned by Community Builder. People have been complaining about the MediaWiki engine long before Community Builder was even probably previewed internally. Most of the complaints about MediaWiki are around not being able to take advantage of features and fixes that were in extensions and templates in Wikipedia or other wikis with newer engines (like, guess what... Gamepedia by Curse).
