That's not entirely true:
- The unhelmeted heads have the same 'bob' haircuts adopted by Battle Sisters
- The wings on the jump packs are somewhat reminiscent of those employed by the Seraphim:
Not to mention that while the armour looks different, it doesn't get away from the fact that those are still WA's own attempt to riff off the 'power-armoured babe soldier' trope, and appeal to Sisters of Battle fans, which is a pointless waste of time, money and effort given the GW range is so popular.
If those models had been some sort of cool alien race instead, then I would have no issue with them at all. Hell I'd be in all favour of them if they were aliens with Protoss vibes (given there are no existing Protoss miniatures), but no, they are just an attempt to take a spin on an idea that already exists in miniature, something WA have been doing a lot with their Fantasy range as well.
Such great potential let down by futile attempts to compete with other companies at selling existing stuff, when they could be exploiting subjects that other companies haven't bothered to instead.
