We now finally have official word on whether or not we'll be getting the servers marked for specific languages at launch, so players can pick a server where their own language is the main one, and the answer is no. Amazon shared the information earlier today and pointed to some community resources that have been tracking where the guilds and players are planning to go:
Server Language Markers (Source)
Hey all, here with an update.
Unfortunately at this time, we will not be adding preferred language tags to servers. I understand there is healthy concern from players about finding and playing with language-based communities, so with tags being unavailable in game, I do want to promote and point to the work that players have already done to start organizing across servers.
This is the latest I have seen, but if this has since been updated please let me know.
There is also a Guild/Community Directory available here and an EU Server Data sheet available here, both of which are solid resources to explore when choosing a server.
I apologize for any inconveniences this causes, but as we are so close to launch the decision was made not to deviate from our current plans; however, we will monitor server activity once the game is out and may be willing to revisit this topic in the future.
Thanks for your patience as the team came to a decision.
