If you're bringing 2 pods, I assume you're dropping in Njal with the Long Fangs? If so, are you using Codex powers, or Divination, so that you can buff the
LFs?
I'm not sold on the idea of using more than 2 Storm Shields per Thunderwolf Cavalry unit... They're pretty point-heavy to begin with. My recommendation is use 2
SSs for the 5-model unit, 2
SSs for the 4-model unit, and one on the 3-model unit. For the Storm Shield models, let the
SS replace his
cc weapon, keeping the bolt pistol, and giving that model Mark of the Wulfen - it more than makes up for him losing that 2-
cc weapons bonus attack (and he still gets the bonus attack for the wolf, in addition to the
d6 + 1). I'm also not sure about the frost weapon. You've got 4 attacks per model (not counting charge bonuses or the fact that your
SS+
MOTW model could have 8), over 12 models, all with a chance to rend. The Frost weapon gives one model a +1S (or +2 for an axe, but then you're definitely going last in
cc), but then none of those models can rend. Math hammers aren't reliable, but it still doesn't seem worth it for 75 points. With 5 Storm Shields instead of 7, 3 Marks of the Wulfen, and no frost weapons, you've saved 120 points, and your
TWC may even be more effective for it. That 120 points could get you another unit of 10 Fenrisian Wolves plus a Long Fang with any weapon you choose.
Of course, this depends heavily on what you have built and modeled...
Even as is, though, you will be chewing up a lot of stuff.
