"While "Livestock Breeder" may be a better term, it's a bit clunky. Imagine coming across a "Rhudaur Hillman Livestock Breeder" in Angmar lol."
Yeah, would be pretty clunky I guess. But like EpilepticMoose says, "Breeder" works just fine as well.
"The reason I didn't want to put in Aurochs was because they will attack you if provoked. While it makes sense for Dorwinion, it doesn't really work out well for the player. Not to mention that they're the "wild" form of cows, the Dorwinrim probably hunt them like we still do deer in the real world instead of cultivating and farming them."
Good points there, totally forgot about the Aurochs attacking you to tell the truth.
"I thought about the Morwaith but they don't really have many meat food sources out there besides Lions, Zebras, and Rhinos but those don't seem like farm animals to me. Correct me if I'm wrong, but I believe cows, pigs, sheep, and chickens don't even spawn in the F.H. Grasslands (at least, that's what the wiki says)."
No, those farm animals don't spawn there. I had just woken up when I replied to thus suggestion, and I honestly can't remember why I suggested Morwaith. But the Rhudel are a good addition (assuming you haven't already added them).
Does anyone here know how to quote? It looks so much neater than these quotation marks. Is it a PC only thing? Probably. The internet treats us phone users a bit to harshly XD
