For what it's worth, I am a 'NA refugee' and I know my thoughts may not mean much in the grand scene of everything, but let me say this: NCWest is basically handing their market over to you on a gold platter.
Your Classic launch could have 24h activity and really pop. Look at what happened to NA and learn from their mistakes and mismanagement; don't do it to your EU players. Avoid the quick cash grab and aim for the long game: thriving and populated servers with happy and loyal players who love Aion. I understand Gameforge is a business, and businesses need money, but players would be more than happy to spend their money on you if you handle the game we love with respect, attention and proper adjustments from the KR version tailored properly to the Western market (looking at that Deity HP debacle).
That said, whatever path the Team chooses to take, I hope y'all have a successful launch and the world of Aion can exist within the internetsphere for several years longer.
