There was some original, and understandable, panic at first, when rumors where afloat that Perfect World had downsized the servers after taking over. Queues of over 10,000 people waiting (moving at a rate of ca 3 positions per 10 minutes) seemed to support that. And people -- including myself -- feared that this was essentially the end of the game as we know it.
Pro Tip: Do as CCP does for EVE Online, and keep people informed as to what is happening! Everybody gets that a new Expansions comes with hiccups. It's when the devs are silent, and there's queues over 10,000 platers waiting, when people are getting nervous, as the silence is suggestive of 'Working as intended.'
