It's also worth mentioning that having a higher physical level is a huge advantage. If you're physical level 17, and you start a level 1 job, the additional attribute points that you can add into things like Vitality, Mind, Piety, and Intelligence are going to make leveling that job much easier. It's another way SE encourages players to play other classes, rather than focusing on just one.

Welcome back to the game. Good luck!
