Why are the White Scar armor sets in Horus Heresy made by Joytoy, for example, so much better or more "Aesthetic" than the very simple 40k White Scar models we see in the media? I still don't quite understand this; I'm a newbie. Could you explain if it's just GW neglecting the White Scars or if there's some reason for this "loss of aesthetic quality" in the armor and weapons?
