Even if you said you dont intend to use mods for this one, it still counted as using and no matter on what you said, once you get flagged, you cant avoid them because you already used them once. You cant asking in here for clarification because it already recorded on their database which cant be removed until you get perma banned.
If you wanted to use the mods, dont COMPLAIN if you get flagged because its no use if you ask modders like that. USE AT YOUR OWN RISK, thats what modders said.
As for that, I NEVER use any kind of Mods in this game because I already know that from day one, it already plagued with Damage modifier mods on Global version which makes Devs make ban waves on every week. I play on JP version for 2 years and I still can get that rank without any Mods or Cheat because why bother use them if they have guides to make things easier.
