The beast tribes were an excellent solution but unfortunately you can't frame that in enough areas without it looking silly. And I'd argue the annoying factor that those monsters will follow you much farther and kill you if they're not delt with is pretty dangerous as you're going to get. Granted the Run Away! Option doesn't have to be an entire zone but the leash could be extended quite a bit...

At least for some monsters always, the ones who are truly aggressive and looking for a reason to kill >:}
