Just an update, I've managed to get my subs to 37, and I've got my mains up to 25. It has been quite interesting because having to search for spells for my blue mage has got me around 90% of my exp, and it has really been quite the world tour having to travel to obscure corners of the world for the right family of monster. Now that everyone is on their main job, we are doing so much better than we were previously, to the point I have to make sure we don't kill mobs too quickly before they can use their skills or the group can skill up their combat skills on it.
