I have long campaigned for a "instanced island" for brand new players. Basically I tutorial area that is created at need for a new player character. Once the tutorial is complete the character then goes through the motions of selection a final Continent/realm to join. It would be a way to have an area under direct code control for tutorial explanations and quests, as well as potentially allowing for time to be speed up in order to get a new player exposed to various concepts fast.
It would however be a lot of work.
