Training Multiple Classes/Jobs

[Avorniel]

just be aware that if you got your first class to 30 or higher and then need to level a 2nd class/job for extra skills or requirement for your main class, you wont have any quests for that 2nd class/job run if you did the quests the first time round to get to level 30 or higher,I wasn't impressed by that but I wont de-rail the topic going on about that lol.

To briefly touch on this, as you have, it is thankfully fast to get to 10 on a second job and still not painful to get to 15. If your plans are only to fulfill your prereq then 15 is all you need. You are correct that you won't have quests and need to do FATEs, your hunting log, and XP chains.
