Something else to keep in mind is the development team of FFXI repeatedly vetoed clears they deemed weren't the "intended way of clearing." Contrast that to FFXIV where every single Ultimate has been cleared in ways the devs never expected yet they were still congratulatory. I have a lot of criticism towards how they've handled balancing this expansion and their stance on parsing but comparing their balancing mistakes to the disastrous implementation of Absolute Virtue is pushing it.

On the thread subject itself. Tight enrages are only a factor for the week 1/2 raiders. The dev team doesn't anticipate the average raider will clear the whole tier where playing at that high a level is ever required. Which is likely how they rationalize not needing to reveal numbers. If I had to guess their perspective, it's to simply say, "It may be challenging now but once you have more gear, you'll be able to achieve it!"
