Here is a way that Enlightened CP could be diminished to allow players to catch up more easily.1
Basically, as your CP gets closer to the highest CP the amount of enlightenment you receive is reduced. If ZoS would like help making a system they like I am available for consult.
Basically the premise behind it is that as the proportion of your cp to the highest players cp changes then so does the amount of enlightened cp you get on a a daily basis.
For example if there are 11 players
0 cp, 100 cp, 200 cp, 300 cp, 400 cp, 500 cp, 600 cp, 700 cp, 800 cp, 900 cp, 1000 cp
Then those players would get 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 and 0 cp respectively.
This would make it much easier for the lower CP players to reduce the CP gap.
Sorry for the typos, my computer keyboard is jacked up atm thanks to the baby.
