I don't see the great roleplay that is gained by virtue of the comment, when lazy sufficed, compared to the racism towards a segment of the international playerbase. What has benefited ICly from these words to the impression the game leaves upon someone of east asian descent?
This is pretty much my take.
This was gratuitous racism. There is no place for that in BattleMaster. Talking about fears of "allowing more censorship" is just making excuses for people to be offensive.
Basic rule of operations: Do not be unnecessarily offensive. Do not be unnecessarily easily offended.
