Some thousand is a little over exaggerated, as those who do have that many have been farming this and other places 12+ hours every day. In my experience, I get 0~4 overall ints in an hour at gobies in new source. Just depends on how lucky you get.
coolie zombies are pretty good, but you basically need to have mystic door to be able to npc the stuff without it being a giant pain. plus the teeth are useful. again though, the bugged spawn rates are a problem.
