Guild Wars 2

When asked to volunteer for the bonus movement speed, experience and I believe magic find, if you have a party member on your map, you can volunteer, get the reward and then re-join on your friend, who can then volunteer and then re-join. This enables you to get the buff and still maintain the empty server.

Yes, this has always been the case. However, when the original hour is up, you will get moved anyway to a different megaserver, and without a warning that it’s going to happen.
