We are the Shields of Eorzea. We protect those who can't protect themselves. We are the first ones into a battle, and the last ones off the battlefield, but how we protect the weak is up us. How well you protect?
Are you going to get tons of def, low atk, able to take hits, but not do much dmg to the enemy. Well you add white magic to cure you and you're allies, or maybe add dark magic to dmg the enemy before they get to you and the allies you are protecting.
Myself. I think i'm going to do a mix of def and str. More def then str though. While add some magic def so I can live when I get hit by magic. def > str/dex > magic def.
Not sure if i'll add cure spells yet. Mostly try to put as much def, atk, and hate ability's as I can from other jobs.
All can change once the games come out. This is what I hope able to do once the game comes out.
