There are a few places in LS that I have found that have adequate mob density and no named mobs nearby. Not all the zones are like that. Most folks don't hunt in areas where there isn't the chance of a named popping. Look around the various zones. There are places in ToL and LS I know for sure. I didn't spend very much time in NoS, so cant really speak to that one. Look for areas without named mobs, that aren't in a path for running from one place to another and visit them and figure out if it works for your needs.
I picked a REALLY good place, once... and had a friend /tell me he saw me while he was running from one place to another and that's when I realized I needed to think about others' travel paths.
