EU/NA Dual home server~
They addressed this earlier in the year when they first instituted guesting. If I remember correctly, it has to do with the physical location of each region’s servers, and the way they’re networked.
At this point, they are unable to make it so that your account is on both regional databases.
Whether this will change in the future or not is anybody’s guess, but at this point in time, it doesn’t look very likely.
Right now the only way to play with both regions is to purchase that 2nd account.
While a lot of us are unhappy with this development, especially since many of us planned our guilds with full guesting ability in mind, we are happy that we can at least guest to other servers in our region.
Good luck to you.
What I wonder is what makes guesting technically different to transferring though.
