Just found another interesting comment from a 2013 interview
G: The design documents shared about a year ago mentioned “A Server System Built to Support a Worldless Model”. Does that mean that, down the line, there are chances for the borders between servers to be further blurred beyond the initial cross-server content finder? I’m thinking about the ability to freely travel between servers to meet your friends, for instance, that is being implemented in other games like The Elder Scrolls Online.
NY: Our server is designed in such way that it will be able to support those “worldless structures” down the line, but we don’t intend to make it available in the beginning. There are certain elements that make MMOs interesting: having borders gives a sense of having a home, the ability for rankings among different worlds, PvP battles between the top players of each world, etc. For that reason, down the line, there are chances for the borders between servers to be further blurred but for the immediate future it will be operated on a per server basis.
So when he says XIV is approaching being a game without servers -- and when he said in the past the game's server structure has this technology, with intentions to use that technology later on -- I have to wonder if this could be one of the big reveals for 4.0. I'm assuming this would only lead to worldless structures within data centers. Edited, Oct 21st 2016 9:37am by Thayos
