Just got around to watching your report. Very well done. Interesting list that the ogres brought. All sorts of reasons I wouldn't take that, but there you go. I tend to find maneaters and leadbelchers to be more effective than 2 units of 4 mournfang, as they give the chance to remove some of your chaff. I would just take the one unit of mournfang instead. It also appears that he did nothing with his sabretusks, which is a waste of the best chaff unit in the game.
It was nice to see how other people use skinks. The one thing I constantly struggle with is knowing how best to use them to give me the biggest advantage. It is really nice to see a turn by turn visual rundown of how everything moved to see what other people do with them.
As far as the battle proper is concerned, I too love scar-vets. I think I would put the stegadon helm on him, rather than on a skink chief. The mounted skink chief is just wasting the toughness boost the helmet provides, whereas it would increase the survivability of the scar-vet even more (ironguts are wounding him on 4s rather than 3s).
In any case, great job!
