What? You really think the noble savage archetype is new and amazing? Please. Argue things based on their own merits, not based on how often they've been done before.
Let me give you a hint: a lot of people portray Orcs as brutal warriors- including Warcraft, through most of its history- because people like that archetype. Now, introducing a spiritual side into their race isn't a bad move, not at all. But you're just as bad as the people who want to go full out Tolkien evil Orcs, trying to pigeonhole the Orcs and by extension the Horde into a visually monstrous race indistinguishable in spirit from Tolkien's Elves.
The Horde's current principle is honorable warfare, not diplomacy and flower sniffing. Get it right.
