Well I'm not playing on Aegis so I can't say for sure but last time I checked Ragnarok (the one I'm playing on) had the SMALLEST population, making Aegis more 'active' than Ragnarok which is already full of people (only during EU times though since it's mainly a EU timezone server).

When I said weird time I meant maybe Aegis became very japan time based since everyone could decide where to go to when the servermerge happened. If your server has mainly japanese players now it wouldn't be weird for most of them to be logged off right now and working since it's in the morning already
