I'm actually a bit surprised that a thread like this hasn't popped up already (unless I'm missing something). Anyway, what all do you guys think of the Solar Auxilia? After humming and hawing over Word Bearers and Mechanicum for the better part of a year, I've personally been sucked in by their awesome models.
That said, looking over their army list in Conquest, it seems like the army will play very differently depending on whether or not you base your army around Lasrifle Sections or Veletaris. It looks to me like the two obvious builds would involve either a gunline using the superior range of your Lasrifle Sections backed up by all sorts of big guns, or a very aggressive mechanized army with Veletaris and Flamer Sections. I was actually hoping to fit some of all of the different types of infantry into my initial build, but they seem a bit mismatched given how grossly different their basic weapon ranges are.
Otherwise, the army looks pretty solid - at least on paper.
I'm curious to see what the Bolter and Chainsword community has to say.
