now the only one being elite rank properly assuming he didnt boost is HuStL3
because he is the only one with the achievement but im pretty sure i remember 2 more of them having the elite rank.
this would technically go against the gamebattles rules of fair gameplay because by exploiting this bug they have access to better weapons and armor then I do.
what probably happened is hustl3 exploited a bug and let people use account recovery with his account to get the elite rank and get an unfair advantage in gamebattle games.
