Real maps aren't divided into areas. You don't name each square kilometre of forest.
i agree on the surface (so to speak), but really, the only areas i found relatively indistinct from each other were, oddly enough, the most-named wilderness areas (the 'Peldvale'/surrounding foresty region) - there are certainly distinguishing features in most of the southern ARs.
but agreed, the transparency issue seems a higher priority.
