I also like the combination of Astrolith Bearer + Thunderquake Savage mode. The only thing I don'T like about the Astrolith Bearer is that it is really static.
I like that list. It looks really good. I would prefer skinks, just because its the same number of bodies, and it lets you take either another Salamander or a Gyrph hound. They don't do anything in melee, but 10 warriors won't do much either. They are also pretty damn fast! Just personal preference!
