Well, the merge is done. You can login to the new servers by now.
There were suggestions by the admin in the official forum, about switching event-times each month between EU and US.
However, I doubt there are enough EU-players around still to make this worth it (sadly).
I personally believe event times will be at old US event times - but let's wait if IGG says any different in an official announcement.
I know how it feels, I played 2008-2009 on Aries, then 2009-2017 on Cap&Aqu - US servers only as an EU player. I've always had those bad event times.
Be happy you've had it so long so nice. ;-)
