Atk mod need constant test in which degree can be safe, x5 deem to be unusable for almost instant ban rate even with new account and I would suggest to remove them for good.
If you don't mind, I would like to request x5 Def and x3 Dmg for version 2, see if it still safe from code defense for I can try them and giving feedback later on.
Even just Hard stage story boss, it really is unreasonable hard even tho it's indicated a suggestion for certain level, I clearly build up my team from so many works above its suggested average level but still stand no chance against it. It's become too much clear that they intentionally design them for whales.
Damage rate is good and safe but I like to try at least more Defense if possible.
Please considering about this if you may
