Actually there was a spreadsheet comparison done on what the experience increase was at 7.0 and then at what Blizzard was giving back at 8.0.1, See the below from another thread where it was actually an increase for levels 10-39; and also other areas.
Blizzard gave the illusion that they were giving back xp gain when in reality what they were giving back was a drop in the bucket of what they had added.
Here are some examples. Note the difference between 7.0 and 8.1.
