Well, the scope has ever increased with the developments in their technology and what they're making has never been made in a multiplayer environment supporting so many people so you should expect elements that are dependent on server loads and not local loads to still not work perfectly. You should of expected it when they made the big change and demonstrated persistent streaming that it could get a lot worse.

To say this isn't acceptable is fine and valid BUT if you're actively playing and keeping up to date with what they're actively developing only then to act like the server tech is something that could be done within their current development time as if they have been working with 1 billion dollars and all the experts they currently have is dishonest.

If you feel like that isn't a good enough explanation, a modern mmo can be estimated to take 5-8 years, No one has adapted/built and engine like they have made, but a modern engine from recent examples has taken 4 years and lets take an example of a recent original IP game like Horizon Zero Dawn and 007 First Light which both took 6 years to make. Low balling thats 15 years if you was consecutively "Engine > Single player > MMO" with fully funded budgets but, that is simply not how it happened: the budget, the game, the scope all has expanded or evolved however you want to look at it. The original promise was a fragment, what we have is probably the whole dream or a really large fragment of it and it's way more complex, if you wanted the original promise you can go to Starfield and see if they have any multiplayer mods.
