3) Any starting advice? I usually like to play mages in RPGs, but for a change I want to choose a physical class: yay or nay? (Or is it an utterly stupid question? )
I've just recently returned to the game and my experience is pretty limited, but regarding classes, practically all can be upgraded to more role-focused jobs at level 30 if you have a specific different class at level 15.
In some case, these class combinations consists of a physical and a mage class, so you might want to look into the jobs that are unlocked by such a mix and see if any pair suits you.
