When 2.0 come out you wont be in any servers you can pick what server you like to go to but let's say you in Gungir your spot would be there even if the world get full because you belong there still. But you could move to other server when you making your char over it would allow you to switch and it be the last time you can go to other server without restarting your char. To they come out with a system to allow players to switch worlds.
