Scores are based on rarity of the items, and such ratio between items is not preserved among all possible areas. Also guys who would focus on Baal would be in great disadvantage in comparison to players who would focus only on Pindle or some area lvl85. That's why, for fair scoring, we focus on areas lvl 85, Pindle and Baal separately, even though Pindle and areas are very much alike so they can be combined into one single area.
