DL (lv70 gear) gives you a lot of Vitality, but being a Lalafell I think you should put 1/7-1/8 of your attribute points in VIT.
The Coil requires a lot of Vitality too because it is a "lv90 dungeon" instead of Hard Primals that are lv60-70.
But remember that HP aren't the only important thing, you need Piety (MP MAX) and Mind (cure power).
Spend something like this: 4/7 Mind, 2/7 Piety, 1/7 Vitality.
The rest isn't that important for a White Mage, maybe 1 or 2 total points in Spell Speed if you want.
