If the population dropped drastically, my guess is that we would all be consolidated onto one or two servers. Also, given the way that donations fill so quickly, it’s likely that we could survive indefinitely at 10-20% of our starting playerbase. The only concern that any of us should really have is the time it takes for a new server to resurface if an NCSoft C&D comes down the pike.
I am out of game for almost a month, however, that’s only because of my near month-long vacation in Europe. I will right back to Paragon as soon as I make it back home.
