when I said it all "fit like a puzzle, perfectly" and it was intelligently designed, I was mostly referring to how you could just barely get four FireIVs off in either half of your fire phase before. The way the timers tend to line up is just a bonus. I suppose we all take our own method of knowing where we are in the rotation. Some people check the number on the timer, some people count. The point is that in all of Endwalker, I was able to reliably keep enochian going just based on the imprecise number with very little issue. But now even after beating EX2 at least 80 times on Black Mage alone, and clearing the whole savage tier weekly, I still can't rely on that number with how Paradox works now. FireIV is just too long to do the same method I've been doing until now, and I end up panic-swiftcasting when I might not need to.

And I'm not about to vouch for previous incarnations of Black Mage as I didn't play any of them, but there was a pretty common sentiment from old and new players alike that Endwalker was as close to perfection the class had ever gotten.
