Well i got Final Fantasy 11 + Chains of Promathia since 14.September too (came out with both Add-Ons in Europe on 16th)
and i havent found any quests yet for new jobs, plus i checked some european forums from german friends on other servers and on all the same (no jobs (maybe not yet)),
good thing is i dont have to worry about leveling another (maybe ?-Mage) job, i really hope they add quests for new jobs ect, when US - Add-On comes out, maybe they saved the quests till all have the Add-On!
