My research on this gave me no hope of a solution but I'm going to try anyway.
Shortly after starting the expansions I stopped playing because the maps there are no fun soloing during weekdays and my old computer didn't meet the technical requirements. Now I'm back with a better computer, and I created a free-to-play account to test playing on the North American server, which is at prime time when it is night here. Higher ping but people to play with. So I'm looking for the best way to play on the NA server during weekdays and the EU server during the weekend.
Is there any other solution that I'm not seeing? Any workaround? Any announcement of future features that I missed? Thank you for your help!
