Orcs vs. Humans

To make the fire of rage truly useful, you just need a little bit of skill. Otherwise, the ability itself is great. Along with it, I would also recommend combat shouts (instead of spellcasting for Orcs); you can generate a lot of rage and also intimidate Knights. Also, in my opinion, attack, defense, and resistance should definitely be prioritized in the upgrade path (definitely include a +2 HP ring, and even better, two of them). You can also add leadership, luck, and light resistance.
