Article is spot on, however, it also seems to lean more on the, "they're sticking with their formula too much!" instead of the why that is the case.
The why being, the suits at Square have never been smart. They wanted to set XIV up to "cruise" like FFXI did, FFXI being their largest earner until MID SHADOWBRINGERS! Yes, that's how long it took XIV to actually out earn FFXI. FFXI bankrolled ARR 2.0.
And FFXI got that way by being a high quality world. Yes, it is old and grindy and clanky and was much maligned by your typical Final Fantasy fan when it came out, but almost everyone that played it got hopelessly addicted to its never ending grind. You literally do not have the time in your limited lifespan to finish FFXI's grind. There are players who started that grind in 2003 and due to all of the additions to the game over the years, they still aren't finished and won't be able to finish for close to another decade. And the thing about that grind is that it revolves around making weapons that fundamentally alter how you can approach the gameplay by giving you leaps and bounds of increased player power and often times new, otherwise inaccessible weaponskills and spells.
And players like that tend to be massive whales as well, buying multiple accounts to increase their grinding speed via bot driven accounts and all that jazz.
Square Enix suits have this weird expectation/delusion that the FFXIV playerbase, which relies on churn to maintain its numbers will hook players like FFXI did, but on a larger scale, and that the players will seemingly play just to play. They don't realize at all, not one iota, that XIV's gameplay loop is the breadth of the universe far and away different from XI's. The only long term grind you have in XIV is achievement points, and nobody sane cares about those (sorry Cider Spider, calls'em how I sees'em <3).
XIV and XI both have gear level plateaus, but XIV's plateau never remains stable for a long enough time that it's anything other than an expansion checkpoint. XI had some span of years where it was similar at its very beginning when it was JP only and then again about 7 years later when they finally broke the 75 cap, until they introduced Item Level in Seekers of Adoulin. But even those times of flux had more stability with how important certain gear pieces were/are due to the different nature about how XI's gear works vs. XIV's.
I could go on for days about ladder progression vs. plateau progression, but my real point is that Square's Suits will never understand gameplay loops nor the mentality of the people who enjoy them. They just want the same result monetarily.
They don't understand and didn't understand when 2.0 rebirthed FFXIV that they were using WoW's formula. WoW's formula requires loads of effort put into the game. Like, sure, Blizzard's made other games since WoW first came on the scene, but you know that WoW has been their flagship. Every other game they've made since takes some sort of queues from WoW and has WoW vibes and sometimes straight up mechanics from WoW.
The short of it is, this formula requires constant investment. Constant building of the ladder. Square Suits don't realize that, so they leave Yoshi-P's team to build the ladder with ever dwindling and breaking tools. Ever dwindling and breaking staff. Ever ordered onto other projects staff.
Before now the narrative was judged by most people (most people are fools) as being good enough to make up for the drawbacks that have spawned from this, but now that the narrative is bad, there is nowhere for them to avert their gaze. They have to stare the problems that have been festering in XIV straight in the face.
It's just a little shitty. It's still good, it's still good!
