I was in the same boat about a year ago when as an adult, I go ally just bought an army. Then I saw the state of things.
The passion that made WHFB left long, long ago and GW has no qualms about admitting it's a business and care more about the bottel dollar. The pie chart of successful game stats went very heavily into model detail and advertising campaigns, almost completely covering up the lore portion.
GW sees alot of other table top war games and to compete, it looked at its cash cow, 40k. Models became insane and over the top, along with price tags. They literally tried to completely and utterly destroy all traces of anything before end times (end times, at least here, is considered age of smeg chapter 0). This allowed them to do what they wanted with fantasy models, and decided alot of them now need to jump the shark.
Little did they know, people loved WHFB not just to paint and play, like 40k where just do whatever the fuck you want, but because of the rich lore and background of it all. Total warhammer has proved there is still a great interest in the setting because of the lore, which, ironically, is the one thing they aimed to destroy.
