Damage mod is not risky here. Atleast as of now they arent banning players. A damage multiplier to edit personally would benefit. Sometimes 1 hit version you cant pass a stage because your cp is too low but I found you can sometimes bypass that using x20-100 damage rather than 1 hit as the previous. I use this version and a different one. There was a menu multiplier version but it's no longer being made and I'm not sure why but yea haha. The real issue with this game currently is all the bugged features. Very frustrating when you are competitive or top up alot.
About what your friend is complaining above. Sometimes stages let you clear them with high damage or 1 hit when your cp is around 1/3rd of recommended. Example. My cp is 2x+ million and I can clear stages with 1 hit or multiplier that recommend 47m. When you can control the damage it allows a slight bypass to the cp rule I stated. Takes alot of tinkering around with.
In the future think it's possible to have custom damage 1-999 and defense? Havent gotten to use one since version 5016. Lol
