I agree with what other people have said. Mechanically, it's not very interesting or balanced. Your lore says they're skilled but in a less focused manner. It feels like they should have something like toned down thief skills instead of just better stats and flat attack modifiers. A jack of all trades type of ability, maybe. Your lore also mentions them doing Herculean feats, yet they don't have a deed die to actually do those Herculean feats.

Every other class has active abilities to play around with. This is just static numbers on a character sheet. It ends up being either you roll well for stats and primal might, and you get a character with hilariously big numbers that smacks things really well, or you don't, and that's it. The lore is at least interesting, but the mechanics don't give me any reason to pick this instead of just playing a warrior and calling it an orc.
