They could have gotten a long way with adding lu-shang style quests for simple earrings or something for each job. I would have loved to have something to do with 10,000 metal ore for miner, or 10,000 crystal shards for Conjurer. They can't make the entire game like that, but it would have been very easy and the would have gotten some content points.

But all this content is coming. There's no one that really wants the game to stay this generic and simple.
