Having a modified guild card might flag you to get ban manually from other players as anyone in the lobby can check your guild card
Having 99 kills/captures all max weapons with 0 played time will look suspicious and screaming CHEATER
If your fine with that go ahead but I would say no to tampered guild card
Yup, i recently programmed a calculator with my GC editor to do legit HR boosting and auto scaling of quests counts, monster kills, weapon uses and playtime for my clients who dont have time to play but wanna "legit" HR up. Came across a few of them who had their saves modded by cheats that overwrote with 99 x weapon uses, 99 x kills and cap counts. I tried to reverse engineer to fix their GC before boosting their HR.. This is what i found
1) All weapon uses x 99 for village, hub, ramage, ez to reverse as there are only 14 of them.
2) The WORST : 99 x kills and 99 x captures cheat are applied across all Monsters, both on released and future released, or may not ever be released.. That cheat mod also applied 99 capture counts to monsters like ibushi, narwa and apex monsters that cannot be captured!!...Cleaning up those counts took me over an hr at least.. before i can do any legit boosting..
3) 100% acheivement award page was illegally modded to appear But the true values that triggered the awards were never adjusted.
I am gotta have to write a clean up script soon, because my current script and calculator only addresses what is current released v2.0.0. not anything for future yet.
I am not suprised those who got banned were those with such illegal values in their card.. Seriously.. dont mod if you dont know the game mechanics.. worst too, selling such as services...
