I’m not sure what the best place to put this is, but I would be curious if Blizzard has investigated the potential of using the Google Translate API or another similar API for translating text. I play on the Aussie servers and we have a lot of Korean, Japanese and Chinese players and the communication can be very difficult at times, particularly as their alphabets are markedly different from the Roman alphabet so even getting a rough gist without knowing the language is next to impossible.
If there were some kind of in game translation function, I imagine this would make crossing the language barrier a lot easier as it’s currently difficult and it’s unfair to expect either side to learn the other’s language just for the purposes of communicating in game unless they want to do so.
