Why not borrow the good parts from FFXI?

The RotZ graph shows ~82% of the player base on or past Ark Angels, which would qualify them for Sky.

~18% on Ark Angles, ~10% on The Sealed Shrine, ~8% on The Celestial Nexus, ~22% on Awakening, and ~24% on The Last Verse.

I would argue that this is because most players who couldn't get to that point quit the game, and are not counted in those statistics. I am certainly not one of the 82%, as I never got past the dunes.
