When Patch 4.3.0 was released, the XP required to get from 71 -> 80 was reduced by 33% posted here: http://us.battle.net/wow/en/game/patch-notes/4-3-0
This should correct the values for v10
I've checked databases from 3.3.5 and the values on the v10 repack are the exact same. So reducing the numbers should fix this issue.
