I usually take a pair of Helstorms, mostly because I don't have any mortars somehow.

Not sure how that happened, or why I let it continue. Anyway, if I did have mortars, I might still take a Helstorm, but then again I might not. On the whole, I have to say I'm not real inclined to take any of our rares. The Steam Tank always seems too expensive and performs functions other units often do better at. I've had horrible luck with the Volley Gun, too unreliable for my taste. And, like I said, I do take Helstorms, but their lack of accuracy, even in the much more forgiving 8th ed. rules, can be a little worrisome. Last game one of them took out about 20 of my own troops in one hit

I should've been more careful, but still.
