Fates literally do not scale.

[casker]

sure, add a little scaling, but not too much. scaling in GW2 was ass because everything was perfectly tuned to have you be able to do it. There was never any variety and never any challenge whether you were alone or with a zerg (not a group, since nobody groups). At least in FF14 you can experience difficulty or non-difficulty based on how many people are around. Ironically the non-scalingness is partly what helps lead to some semblance of dynamic content.
