I think the whole "map" thing was in place to make it interesting travel-wise too once you got into the higher Oro kills. Remember, not everyone goes through resets like a brick through wet tissue paper. While it really didn't bring something grandly exciting, it was a "woo" the first time you noticed that you could get there. Subsequent visits were a little more like, "aww...". But with how infrequently people visited, it made it pretty unlikely that you would get PvP'ed in Iwa (if at all possible) fields.
