Thanks for the follow up. Hopefully transfers aren't delayed by much if users are becoming locked from playing their characters.
Actually, for a player who currently plays on an APAC server, there is no effect. You can still play your current characters and even make new ones! What the lock does is stop players who do not have characters on APAC servers at all, from making new ones.
Again, if you're an APAC player who plays on an APAC server, this has no effect on your ability to play.
