I luckily don’t think that’ll hit AOS the same, a lot of models don’t have multiple options like 40K, simply because it was created later than 40K, and began its life with dynamic posing over multi parts, while their is plenty of multi kits, it’s nothing in the scale of 40K, so I don’t think it has the same level of concern. Plus a lot of weapons profiles in 3rd are “choose the model it’s the same attack”
Lore friendly special rules however are what I fear about, that sprinkling of some in lore ability that may be pointless most the time is what makes me feel like the model is straight from the book, that was lost in 40K a lot, but I do hope they have learnt to retain it this time around
