Would it be possible that everyone gets free nation transfers for the first week that the server starts? The reason I'm suggesting this is that a lot of people are saying "maybe I'll go vys... maybe i'll go yllse... or maybe zyp..." but most people have not finalized their decisions yet.
You can argue that in the first week, it's easy to just delete and remake your char but I will give the rebuttal that most people are lazy to redo those first levels. If they had to remake their chars, they rather just stay in the nation they're currently in but if they're allowed to get a free transfer, they're more likely to move. One of the most important things about making DR fun is having balanced nations. This will give players a chance to balance out the nations if they see that one nation is underpowered. Also it gives players a chance to be with their friends if they end up in different places because they played in 1 nation for beta then chooses another for official launch.
