Black sun is mainly for whale players since newbies can't stand a chance to earn points because they will just hunt you and majority of your points will gone instantly. Imagine when you've been killed by players much higher cp than you. They always deduct 30% for whatever the CP who killed you. For example you are 5k cp and you killed by 10k CP. It is better if the deduction is lower than 30% because there's a big gap in CP. Or else create a new server so that everyone with low cp will benefit the spoil of the black sun. I'm sure lots of lower cp will switch to new server if necessary so that they can also benefit from the black sun.

my suggestion was the player will not lose a point if killed by a player 1k cp higher than you.check here:

This game is great been playing for over a year but they add things and more then 99% of the time it isn’t fair to lower cp players only for higher cp players
