This is an extremely fair way to manage the merges. Actually I wish that instead of choosing the same names they were picking 10 brand new server names. But naming them after selection is a pretty fair way. Server mergers are sucky so its good they could come up with a method that will remove any exclusivity from the result.

The only thing that sucks is that a Linkshell (or other group of people) could collude to pick a certain world to merge to and then announce a different world to the less savory members of their group in order to ditch them. I'm sure this will happen in some form and there will be a lot of QQing when people realize that they moved and none of their 'friends' are in the same world.
