3 million XP in 6 minutes! I can finish my leveling with just these quests :)

This is a great "find" if you can barely play, because you can level "over time" but if you plan on leveling at a steady or rapid pace, this does literally nothing, glad you found it though if it fits your playstyle

You're correct that it's not much help for the rapid content consumers that want all their jobs at max level yesterday even though they won't touch those jobs the rest of the expansion except to update the gear sets.

But it's fine for those who are trying to level at a steady pace. I prefer to level alt jobs at a steady pace. I've got everything to 90 except NIN (and BLU of course) because I've been doing it at a steady pace and NIN will be at 90 sometime next week.
