Unfortunately we do not offer the possibility of transfering your characters between servers.
As for the "European servers", from the EN comunity; Vidar is the oldest while Idun is the most recent one. If you are wondering which one to join, you can create a character in both and decide later where to put your efforts
After some digging, I found in another post on the forum that the drop rate bonus only applies to groups. I was grouped when I was getting the increased drop rate and solo when I wasn't. I was in Chaz farming tier gear using housekeeper luck potion both times. In previous drop rate bonus events it applied to solo players. It's a shame that RoM did not make that information known in the event announcement. It's going to upset a lot of players.
that information was part of the Event announcemnt, please check it Here
