The only gripe I have for groups who translate with the word "Master", they always uses "The Master" when the MC or equivalent is mentioned which does not make sense. Its like everyone is talking about someone else rather than the person they are talking to or as if "The Master" is a title rather than a respectful term for a teacher in a specified subject.
I mean, grammatically, it would make sense for it to be just "Master" or in cases of talking about them with other parties, it would be "My Master" because it would make more sense rather than using "The Master" which would indicate they were talking about a renowned person every single person in the whole world should know about.
