Some more in depth in-game tutorials would be nice to see.

But, if nothing else, I'd at least love it if they added a mandatory requirement for jobstone being equipped in order to queue. Adding a little notice for the quest availability it during msq would also help. The job quest opens up a little after the sylph quests in MSQ, right? Maybe they could add a quick "Hey, your job quest is ready! You can do it for a huge stat boost and lots of new abilities *hint hint*!"
