It was primarily in the equipment and int 1 really, really sucked. Marks + halberds was no slouch. Equipment defined a lot of what made troops "elite" in WHFB, but it's been a really long time since i've played 8th edition and I honestly haven't really thought much about it much since it got squated. Maybe the difference wasn't as big as I remember it. Either way, with the proliferation of 2wound infantry in AoS, I could see a situation where they become 2 wound characters. I just don't think it's supported by their past existence anymore than them being a 1 wound better-than-average warrior is.
