I've even thought about building whole veteran units with scion models, since they look cool and have carapace armor. But it's way too expensive.That kit is probably one of the coolest kits GW has come out with IMHO. I've wanted them since first seeing them, but I tend to not buy models without having a place in a list for them. I've play-tested it using the models I used to play as Stormtroopers in the previous edition, but they haven't grabbed me. It's exceptionally rare for me to even think about the Elites section of the AM Codex. Were I to get them I would likely use the models to build up my Inquisitor's warband over using them as Scions, with the extra bits showing up for flavour in my Guard.
