i'd like to make a suggestion.
make it so there's a a power limit on individual hitting . for the sake of fairness make the limit within a few million power. this way your fighting those who are more equal to you.

Allow growth, not all players spend money but they make the game!
Need to introduce a level bracket system to allow players to grow and make the game better!

Outside KE....Lvl10 can hit lvl 10 to 5.. Lvl15 can hit 15 to 10 lvl20 can hit 20 to 15

So it becomes bracketed similar lvl can hit each other, will help growth and then in ke all all! 👊

Would work a dream
