90 please. Leveling through pandaland is tedious as is, once this expansion is over with leveling through pandaland will be complete and utter torture. Blizzard has said many times that "linear questing" really hurt cataclysm, but honestly leveling through cata's linear zones is the smoothest leveling bracket right now, at least for me. Leveling through pandaria will be torture once the next expansion comes out, even if they cut the XP in half.
