There has not been a single major patch without a critical issue since Endwalker.

I disagree. PvP overhaul was great and very well received. It revived what was basically a dead mode. The raid series has been a blast so far. Aglaia has been well regarded as one of the best Alliance Raid tiers. DSR Ultimate was loved and is one of the hardest fights ever designed in the game. We've got a ton of new content coming in 6.2.

They've had some hits, but also some major misses. CC and Aglaia were great. DSR is something I can't really speak on, but it's apparently doing okay. Meanwhile, they've been cutting corners in some places, like with Hrothgar and their apparent need to re-use job gear for CC rewards when, in my opinion, there should have been more unique sets given by those vendors. They've also messed up their housing lottery system is a really bad way. It shouldn't have taken them a month to get it working properly. And data center travel is apparently not doing so hot right now. Could just be the traffic or a bug, but either way I don't think they tested it properly, or at least not enough. I haven't seen them fumble content design back-to-back like this for a while. Think the last time this happened (for me at least) was back at the beginning of HW when they released Diadem and Verminion and they both died shortly after.
