It was delayed for more QA time as well as to TRY to mitigate this issue. They never said they could solve it in that time, but they made the attempt. a computer can only do so much, have so many users accessing it, a server is just a bigger computer in the long run. You are correct the bickering back and forth is ridiculous. both sides put down the other and call names and attack. we just need to work with the situation and just get by sure queues are long, but that is NORMAL in an mmo as popular as this. New World had longer queues and they had just as much vitriol about a game that just launched. SWTOR when it came out was besieged by people that during it's making supported the decisions and then decried the result of those decisions: like we do not plan to have a dungeon finder queue to be like WoW and then when it came out people cried "where is my dungeon finder!??!!" and didn't like the game. then when these people hit end game they cried why isn't there more to this? well they skimmed by everything only doing what they had to in a rush to get to the end game, and missed all the extra story that was put out in other side content, yet their content was actually fairly deep for a brand new mmo. but they expected 7 years of content on day one.
so yes it's ridiiculous, but there are problems that none of us even know about in the development of this ex-pac.
