No, that is a playerbase driven malady, generally found on the more populated servers where people are still operating the old elitist mindset that you need to have the best stuff to never be holding your group back. As if you needed such absurd power to beat every little thing.
In fact, if you look into it deeply enough, you will find that for almost the entirety of FFXI's history, contending with the playerbase of FFXI was its endgame's greatest weakness.
Like in XIV we all know about the crappy deal with PUGs and PF and leaving after a wipe or two. Or people making clear parties lying about progress etc.
But in XI to even get invited to parties, you had to basically advertise yourself as best as you could. Like in the old days you set up a search comment for people to read while they built their parties, or you would read those comments yourself when you made parties. People would put notable pieces of gear they had in their search comment, or their own stipulations about what they would accept from a party. The more meta friendly a job was, the more sassy/diva like a player could be. Years of honing that mentality means that a lot of the old salts won't accept anything short of the best, though the sensible ones have come around (though these sensible ones also usually wind up being people who didn't really become vocal/get to endgame until right near when the Abyssea era was ushering in, people joining right at the tail end of 75 era).
There's actually a podcast. Or was one. I don't know if it's still going. But some major community figures who have made the leap to content creators do/did a podcast where they talk about FFXI. Subjects differ, but there was one where they were talking about the state of the game before Master Levels came out. Two out of 4 of the dudes on the podcast were players who'd started in 2008, but by then had played for 12 or so years. They had still managed to pick up that, "Only accept the best" mindset. When one of the more casual folks on the podcast (Hunting For Games) said that he was in a group that beat Warder of Courage (Item Level Absolute Virtue), and he had been on Blue Mage with only 1200 Job Points instead of 2100(Mastered Job, though not to be confused with Master Levels), the other pod cast folks were just silent with shock. You could tell they were thinking, "Whoa, your group was full of scrubs, and you were scrubbing it up, and you won somehow?!" They didn't vocalize it, but it was writ plain on their faces.
I myself actually took quite a number of years, and hearing horror stories from ex-FFXI vets who embraced XIV to change my own mentality about that, too. I'd always been a bit against the grain in XI's endgame community as it was. I never reference spreadsheets, parse, LUA, mod, bot, or anything like that. I also never clamored for the super duper +1 gear that players price gouged due to its rarity for that little tiny +2 more atk or +2 more acc (which you'd pay like 20 million more gil for). I just played the game, and did the best I could with info from forums/sites/my own observations. Like back in idk, pre-2007, many folks never realized/believed that Warrior's 2hour(1hour) skill, Mighty Strikes, did make physical weaponskills critical hit. Normally, in XI, unless a WS says it has critical hit chance, it cannot. Warrior can circumvent that on any WS, and always has been able to, but the log doesn't display that, only much higher WS damage when you do. So for years I dealt with people asking me, "Why did you waste your 2hr/part of your 2hr by weaponskilling during it?" to which I'd say, "Did you not see the damage? Mighty Strikes works with weaponskills!" To which I'd mostly get the response, "NO IT DOESN'T! THAT WAS JUST WSC MODIFIER VARIABLES!" or rarely, "Wow, I didn't know that!" Only for just a couple years to pass, it became common knowledge, and then everyone acted like they knew it worked that way all along.
BUT
Even in the new age, on lower population servers, there is still enough of a mindset about REMA(and now Dynamis Divergence/Ambuscade Pulse weapons) vs. Non-REMA havers, that basically if you haven't built your job a super weapon of some flavor, then you'll be expected to play support like BRD, COR, WHM, or GEO. In fact, for years after about 2015, endgamers expected returning players to level Geomancer and play Geomancer to a significant degree to basically be a buffing bubble bitch, and it took at least 2 or 3 years before that became unsustainable, and people started to request multiple jobs, so that the group could rotate through job types to alleviate boredom/be more welcoming (but also SE making content resistant to GEO).
