Well, considering I'm not a player, my opinion matters very little, but I just can't seem to enjoy these too much. Maybe I'll "get it" as the wider range gets more "Sigmarified", but right now I can't help but feel that these guys feel too high-concept, with little to no grounding and thus not really something I manage to feel invested in. There's the lack of actual dwarf faces, for examples, though I'm sure a little bit of conversion would fix that for an actual collector.
I mean, they're cool, I've probably just not updated my aesthetic expectations to the Brave New World of Age of Sigmar.
