You never go wrong in assigning all the stat points to your main attribute for any of ur respective jobs, a.k.a VIT in tanks' case. STR on tanks is debatable. I am not saying no to it, but I just think that in the high-end fights of the game, you do need the maximum amount of HP u can get from your gear. Maybe on some not so high-end fights, you can go with STR accessories... dishes out more DPS, which can make things quicker(or whatever).
