tbh I wish There was another way when your leveling your 2nd class/job but since the quests don't appear after you have done them once with your main class your sort of forced to,I hope they re-think this and make the quests appear with each new class/job on same character but with limited gil/rewards.Till then I am taking a step back as the current fate system with zergs and whining players if you kill the main boss to fast just ruins the enjoyment.
