True to a point. I'm not saying let them get shot to pieces. More to the point get them into combat but should your opponent fixation them so much the better. My whole point with Black Orcs stands: in terms of our Special Choices they might be the best aside from the obligatory bolt throwers.
what about using the black orcs entry as chaos dwarf immortals? use suitibly bulky models, and take a Bull Centaur Hero in them to make them LD 9. suitibly more impressive than chaos dwarf warriors with great weapons, would allow for more dynamic poses with larger base room, and would accuratly represent their rules i think.
