after long long research on the game with all simulations possible for ban, i tested it 7 accounts for 7 things and found. Com2us cant track the amount of damage you make , but only the speed. two things to note. there is ban via gamemaster and ban via autoban system. gamemaster bans when your profile is reported. that happens because you are defeating arena 6* monsters with 3-4* monsters. these are called impossible events and players report you. secondly, maintain safe 2 minutes game play on all dungeons . TOA is very very risky. mind it. i have had emailed c2u to find out reasons for ban. pls take care of these two things and you will not get ban. make it look you are normal player. thats it.
