Right now I am doing the ixal dailies to level all the crafters at once (5 levels or so and then switch, etc), standing around in Limsa playing final fantasy music on bard, and running in-progress mentor roulette as healer. I would say the atmosphere of the game and the community keep me hanging around. If I saw FFXIV as strictly a source of rpg progression and nothing else, I probably would have quit long ago.
