Yeah, the population did decrease. But there's still a ton of people on Apoline and more joining every day. Teva is also kinda empty but I don't play there or on Bijou. When its around 2:00-3:00 AM in the morning for me the entire server is practically empty. You don't see many people running around and you can always get into two of the lower Kingdom Quests. I still can't get into Gold Hill because I keep forgetting to pay attention. @_@
