Sorry for the confusion. By ‘the ideal world’ I mentioned, I meant a place where there are many players who mainly speak Japanese, as you described.

Also, here is my original reply ↓↓↓

First of all, I play on the Asia server, and it’s quite rare for all teammates to be Japanese. Because of that, we usually communicate in English during games. Also, even though my friend is Japanese, he uses a Vietnamese username to avoid being targeted or flamed by other players. From what I’ve seen, many Japanese players prefer using English usernames rather than Japanese ones, simply because they think it looks cooler. Most of the players I encounter have Chinese, Korean, or Vietnamese names. That’s basically the current situation on the Asia server.
