Blizzard announced that there would be 100 additional "Paragon" levels after a player reached level 60. I'm not sure if they announced exactly how the increase in XP would work, but I was wondering if anyone knew the total amount of XP needed to get from Paragon level 0 to 100? A formula would also be helpful.
(The only detail I was able to uncover from Blizzard was that the first paragon level would be roughly the amount of xp it took to get from level 59 to 60)
