I'd rehash the 'hunt' thing - if you want to suppress inferior beings such as goblins large-scale and efficiently, a sole individual, unless a he's freakin' dragon, will not do.
Hence, I'd move away from the hunt and call it... intervention? Nah. Strikes? Campaigns? Genocide is quite methodical, actually.
So, they might have a military rule, with medals and distinctions playing a major role. If they are so superior, perchance with high regenerative capabilities, they might have medals for "losing a limb and fighting on". Of course they'd get distinctions for kills. I see them having a magic-tech thing that stores the blood of their kills and can conjure the images of their victims - it may be forearm armor combined with a retractable blade?
Also, they might be capable of a great degree of adaptation - if wounded often, one would develop bone armor; excessive training would lead to great muscle and bone structure. A scout or sneak would try to avoid getting wounded and exercising too much, as to prevent excessive growth and stay nimble.
