Sounds like Hunter from ffta from what you described though they captured rather than killed/scavenged(but i can see it fitting their kind of lore). Doesn't really sound all that much like Sheperd, i imagine Sheperd collecting milk from cattle, wool from sheep nothing that actually kills the animal because the sheperd is only taking what the animal does not need to live. To me they should be two seperate classes(they use different tools as well), one based around raising livestock and reaping the benefits the other around setting traps, capturing, killing and excavating like you said.
