No, that's not what I was saying. I mentioned it because it was easy to talk about and it is an example of something some MMOs have done to stay relevant. If you show someone who's never seent his game before some screenshots, they will probably prejudge it as ancient looking. You and I have been here a long time and can appreciate the work, care and attention that went into it a lot more because we're used to it. Even though I look back at XI's appearance fondly, I'd hardly describe it as a "fine oil painting" that can't be improved in any way. It looks great, but it's showing its age. The great masterpieces of paintings don't show their age because few to no artists of today can match the quality of their work, unlike computer graphics which can always get better because of advancing technology.
But again, that's just one example of things games have done to keep up. There are many other things, most of which tie in to adapting to the changing needs and wants of your clientele, something SE has been pretty slow to do in XI (Ten+ years to get a range indicator (9 I suppose if you count the color changing arrow thing) function? Come on.).
That's incorrect, as FFXI peaked at a little over 500k subs. For XIV, we only have total accounts data, where the last number given was 2.3 million accounts. Although that isn't subscriptions, in its last financial report SE said it had a total subscriber base of somewhere in the ballpark of 1 million total players. Given XI's state at the time, and Dragon Quest 10 only being available in Japan and the surrounding area, it is likely that XIV represents far more than half of that subscriber total. XIV has more players than XI ever had in any point in its history. And I can tell you, it has not a whole lot to do with the game itself. It's mostly about marketing - SE has done a far better job marketing the game than it did with XI- it could have been as successful, if not more, if XI invested more in marketing it outside Japan.
(Unfortunately, one of the few sites that tracked numbers for all MMOs has stopped updating the site because everyone has stopped giving out numbers. Not just XIV, not even WoW is giving out its numbers anymore. EVE, which was reported to still be growing in size last year, stopped giving its numbers as well. XIV isn't on the charts because 1.0 never gave out its data and ARR came out after this site stopped updating. But here's the link to the chart that includes XIs numbers:

Unfortunately there isn't any other sites that devoted themselves to tracking this data, and as was said, most companies don't give it out anymore.
