Ghastley, I've only used Erandur for a short time beyond his quest - so my impression is limited and I'd certainly yield to anyone who has used him more. I found him pleasant, but he ended up taking a knee more often than, say Illia, Aranea or Brelyna. I do recall that he did well in terms of not delivering friendly fire.
The idea of a Mystic Barbarian orc is delicious. As you know, I've loved orcs ever since Buffy met Mazoga. In Skyrim, each stronghold seems to have a shaman/wise woman spiritual leader so the concept seems completely natural to me.
