The first rule of warhammer is:
You do not talk about warhammer (JK)
The most important rule of warhammer is ignore GW, for they are gay and they only love what is green and does not grow.
They may have re-re-re-re-re-re-re-re-re-corrected themselves again, but I think the 40k rules for lost and the damned still apply. But rules are different to lore, once it's written it stays lore, I mean look at Malal, nobody cares what GW says.
I think a scripted battle with a few marines would be kick ass, do you disagree?
