MastelaRO is highly not recommended.
I was recently banned due to being accused by the head GM. They accused me along of 8 other people of using WPE maya purple filter and botting, which he has no proof of whatsoever. In the end he banned my whole guild, also with the fact that he was calling us racist. Our guild name was KKK and NAZI United. Racist? He used nigga in every sentence.
Overall, this server is highly not recommended. Economy's unstable and the head GM never logs on, and when he does log on, he goes around banning people like a Nazi liberating jews.
Stay away from this server.
One review is enough.
