Ive been playing for a week, gladly no ban so far. I always make sure the combat gameplay finished not too fast and not always winning each battle. Ive using the dmg mult up till 15x, 10x defence, and increased critical chances.. i think the only thing i suggest is try not always get mission completed.. try sometimes u fail 2 or 3 times in mission.. prob could least your chance to get ban.. and then increase "your luck" remember blanc said. Good luck everyone.. i hope my acc not get ban.. cus i get blanc :)
