I was thinking of Dragoon and Soldier at times, but I definitely can see quite a lot of Black Mage in your responses. Black Mages are often viewed as being rather supportive in their own way to the party, but they don't baby others all the time. They're loyal, pretty fair-minded usually (sometimes it depends on the character themselves as there are some exceptions, but quite a few of the Black Mages that initially came to mind for me do fit this trait)...and some of them can be a bit head-strong too (such as Rydia and Palom in certain instances). Quite a few Black Mage characters also tend to be a bit more reserved/introverted, are rather balanced in terms of their energy levels and emotional reactions to things, fall in-between being a leader or a support figure for a group, and tend to be fairly calm...especially when it comes to battle tactics in games if not other situations (though usually it is both). :D
