Just to give you an idea, lets compare FFXIV's patch cycle to WoWs. This is kinda old info, but here's a timeline someone made of the content patches from ARR-Shb compared to Vanilla-Shadowlands 9.1. https://i.redd.it/qut9puhli5i71.jpg

Yeah as you can see, WoW has almost an entire year long worth of drought compared to the measily 4 or so months schedule, and even then the patch in of itself gets sprinkled gradually within that time frame to fit everything it has to offer. So I have no clue what you're even talking about, regarding "quality content". Apparently, having a big side recreational side activity, alongside new types of midcore dungeon content, quests and raids is just nothing for a patch.
