Scenario quests question

[Niwashi]

I don't have any idea what scenario, main storyline quest my char (new job) has already done. Have no quests with the flameQ in my directory for this one, and when I go to quests completed it gives me all of the quest my main has done!

If you're still playing the same character (your main or higher level character) and just adding a new job, then yes, it will show all the quests you've done with that character. While each class and job has its own questline in class/job quests, they don't each redo the main scenario. That one is once per character, not once per job.
