I just don't find that as thematically compelling. I like the social unrest idea better, maybe it's just a personal thing. Basically "those guys over there are living in the lap of luxury away from the battle lines, and I freaking hate them for it." It fits thematically so well, because why are these guys warring so much anyhow? This helps tie that idea up in a really nice little bow (jealousy is the roof of all the evil here), and so on.
I guess Unrest could be Jealousy instead, but that feels a little strange. Woe is strange too, but in a funny way. Jealousy just seems strange, so I'd prefer something else.
