Orcs would be an autobuy for me. I love orcs, i'd played them in literally any fantasy setting that lets you play them.
Not sure how Terrinoth orcs are but all iteration of orcs ive seen theyre always burly and durable, having much higher strength and resistance to pain than humans. I could see Lethal and Protected being an army-wide thing for them, though i'd hope they do something a bit more interesting than that.
