I have been around long enough to know what Warhammer Fantasy was.  Warhammer Fantasy was a very small set of themes mixed together and given its own flavour. Coincidentally, Age of Sigmar is also a very small set of themes mixed together and given their own flavour.  The difference is that as a setting there’s far more gaps in the lore for players to invent their own things something that the old world didn’t have. Here’s something that might blow your mind.  There’s nothing at all to say that a simile of the old world doesn’t exist somewhere in the Mortal Realms.  A place where a nation of humans exactly the same as the Empire lives.

Age of Sigmar, even though YOU don’t like it, wasn’t a mistake because ultimately it hasn’t harmed the company.  It’s doing at least as well as WFB although I would argue it’s probably now more popular in terms of sales but it’s a product over which they can exert much more control in terms of copyright.  Overhauling the world was never about whether people liked it, it was purely about copyright and control of the IP.  Had GW gone bankrupt as a result of the cancellation of Warhammer Fantasy Battle then possibly you argue it was a mistake.  But GW are currently sitting pretty enjoying what is arguably the most successful period in their entire history so it’s really hard to see how Age of Sigmar can be deemed a mistake on any grounds other than a few bitter ex WFB players don’t like it. Sadly for those players, success is not measured by their own personal satisfaction but on sales.
