We get it, you like AoS, some of us do not.
You're quick to dismiss anyone who's bashing AoS as a cretin who's stuck in the past, but I think you need to consider that a lot of the older players and collectors (I don't know how old you are Old Stoney) grew up with WFB, it kind of mirrored other things that we grew up with too like maybe Robin Hood, King Arthur, LOTR, dare I say all conventional, somewhat grounded versions of fantasy mixed with historical realism, and this is what WFB was born out of in the beginning.
I do fully understand why GW made such the monumental shift. IP was difficult to protect, their fanbase for Fantasy was maybe stagnating and ageing and the rule set (I don't play so can't be 100% certain) was I believe getting more and more complex, putting off the younger generations as it was too difficult to get into. The youth of today has grown up with technology and Marvel superheroes, not swords and bows so yeah pseudo dwarves with lightning rifles and massive beefcake golden boys are maybe a little more relatable to them. Bright lights and colours and all that.
It's the fact that it was so massive a gulf between the old and the new, nothing is familiar anymore, silly names included, probably what GW were going for. It is aimed at the youth and if you are into it then that's great, more power to you, but it understandably closed the door on a lot of other people. You can't replace LOTR with Flash Gordon and expect your fans to lap it up and not rip it to shreds.
Finally the comments on the new Old World are entirely valid, what's the point in reviving the Old World if any new models are a full head and shoulders above their counterparts from yesteryear? Why bother going back in time if everything you produce is going to be more magical and whimsical than it previously was?
