And we are fine with the new players coming around, don't misunderstand.
But yesterday, for instance, on the EU server at their evening, the queues were up in a 4-digit area which caused a lot of players to wait for over 30 minutes to get logged in. There were also issues that the server wouldn't read character data properly and made renaming/fantasia use difficult.
While the rush of new players did affect the queue, it's mostly that quite a few players remain logged in the game, afk, and clog up the servers for others, who want to play the content or with friends.
