To my knowledge, I believe some lines of cures in particular #4 or 5 has some small VIT mods. However, I dont think it would be significant enough to swap VIT gear in place of MND, MP, -enmity or cure potency.
The real reason to wear this is for the Enmity- which may be more useful for high hate spells like Cure IV than a few more HP healed from another hat. It's better to macro in a Cure Potency or MND headpiece for Cure V though.
