I suppose there's some subjectivity to my claim. Maybe it's not accurate all the time, or in every possible way, but it is accurate much of the time for me. At least it is in any way that's player power related as far my main job is concerned.
There are often significant periods where I have the best gear I can get for my main job and there's nothing for me to pursue as far as player power goes (without considering alt jobs). That leaves me feeling free to pursue just about anything without fear of falling behind. If I don't need tomestones I don't have to run my daily roulettes. If I have my main job at max level and max geared for a particular patch, I can go futz with alt jobs, collect Blue Mage spells, or decorate my house, and never "fall behind" from my perspective.
I guess a better way to say it would be that FFXIV gives me a break from the treadmill periodically and let's me enjoy the fruits of my labors for a bit before the next content patch comes and adds a new tier of player power to pursue. During that "down time" I can engage in any frivolity I like without fear of falling behind.
