Second, you're whole post is kind of proof of exactly the criticism I reiterated, that the WHFB setting is a hodgepodge of different influences smooshed together with very little unifying it together.
It's a literally
. That doesn't necessarily mean you are generally an ignorant person. It'd be like if I gave my opinion on horseracing or something. I might feel very sure of myself, but it'd be an opinion springing from ignorance.
That's not intended as some sort of cheap insult or aimed even at you particularly, but rather the opinion. But it is a fact that it is an opinion born someone's out of lack of knowledge of the subject.
D&D is a "hodgepodge of different influences smooshed together with very little unifying it together" (what with Tolkien's Elves - except short - adventuring alongside devilmen and robots, and Vancian magic cheek-by-jowl with nigh-Biblical clerics and New Age-influenced Druids), as are the vast majority of settings for it - especially early ones like Greyhawk, Mystara, and Dragonlance. It wasn't really until the Grey Box FR and Time of the Dragon that people even started making vaguely coherent D&D settings (so the later 1980s).
To sneer at Warhammer on that basis necessitates that you sneer at an awful lot of D&D settings, unless one is to be truly hypocritical. And if you do sneer at Mystara, Spelljammer, Greyhawk and other "messy hodgepodge" settings (I love Spelljammer but it's ten times more of a hodgepodge than Warhammer is now - maybe back in 1990 it was a toss-up, but Warhammer has developed, and Spelljammer hasn't), well fine, that is a viable opinion. But do you?
I think it was a recent article on Cubicle 7, but I will see what I can find.
Hmmmm. I've google'd that and looked the Cubicle 7 website and I can't find Priestley saying anything about Warhammer in association with them at all. Are you sure this wasn't just some youthful Cubicle 7 dude speculating?
EDIT - Only interviews I'm finding that are even Warhammer-related are with Emmet Byrne who is definitely too young and too not-employed-by-GW to say anything on this - and indeed reading the interviews, he doesn't.
However, Age of Sigmar Soulbound does seem kind of cool so there's that!
