What Final Fantasy XIV has to offer at this point is fairly limited, especially for anyone who has been playing for longer than a month.
This is very misleading. Perhaps for people who are super-hardcore and work to a timed schedule and repeatedly do things as a group every day, this might be the case. I've been playing on and off for a year and then consistently for a year and I still have loads of things I've not done, because I've been doing things very differently to you. My group of friends are not often all on at the same time, I enjoy teaching new people how to do things (which generally means failing over and over while they learn), I power-level friends on occasion, I help people I don't know do quests that only help them instead of helping me, etc. I don't have all jobs at 50 despite playing this long, I've not completed a couple of the dungeons yet and I've not beaten a single primal (although I should have by now, to be honest, I've had very bad luck with parties - grrrrr).
