It's not that Shrike's mini marine version looked much better… Despite their "true scale" upgrade, Primaris models are still rather limited in poses. Here's hope for some conversions.
Regarding the new Nagash guys, they seem to be another reinvention of an older range, Khemri in this instance, in order to trademark it. While I do appreciate the experimental spirit (and was an early adopter of Stormcasts and even their steampunk dwarves), GW's latest attempts with submarine elves and now fantasy Necrons have failed to impress me. But each to their own. This new range might at least provide some nice bits for Necrons and Tyranids.
Looking forward to the Adepta Sororitas release. Ordinary battle sisters look largely unchanged, so I'll definitely paint some for Kill Team.
