The difference here though is not that this is a launch specific thing, they had the exact same issue this spring when there was a mass influx of players; at least in europe there has always been a queue since around april/may this year (despite small about 200-300 people over all, which practically meant around 5-10 minutes queue time).
Even at that point it was known the server capacity was too low, to mitigate this SE stopped selling final fantasy. Now they obviously sold a shit load of endwalker licenses and this includes not only a influx of new players but a huge load of previous players that been on hiatus awaiting the new expansion. At the same time they've been driving advertisments and made the "trail/free" version a lot more generous in hope of getting additional people hooked. While at the sametime making little to no efforts in expanding the server infrastructure, now the official reason is the pandemic; yet YoshiP just recently said they _will_ expand the current datacenters with the hardware they _already_ secured, and you white knights still believe this company.
