The exact same thing happened to me ... I got the certificates the legal way and they started QQing...After getting pissed of 3k crits from archers I desided to make one too to try it...Anyway I tried it didn't like it and wanted to log back my duelist but it seemed it was banned ... I asked the gm and he told me he will remove my certi cuz it wasn't allowed... lol wtf certificates are part of the game... Its a part of the pvp....Fix the god damn archers.... no one likes to get 2 shoted... :|
