I think that it should be mentioned as well that if the rangers were (which is extremely unlikely) given the NwN version of HiPS it would be significantly better than the DnD version rangers get as in DnD they are only allowed to use it in natural terrain where shadow dancers can do it anywhere there is shadow. If we were to give something comparative to rangers than a secondary HiPS feat would need to be made that recognizes the check box marked when the area was created.
