Alright, I'll make a few lists with Gorbad and Wurrzag and see which one looks better to me. Thanks.
EDIT: I think I'll use the new finecast savage orc shaman on a war boar model for Gorbad so he fits with my army's look, problem solved. I also have another question. In the Night Goblin entry it says that they may take short bows in place of shields (they can't take both), but the Night Goblin spider riders entry says they can take short bows, even though the equipment section says they are armed with shields. Since there's no specification, I was wondering what to do.
