Guess that's a old habit from the old WHM so I still use Cure when I don't need big heal.
But it is true that now that mana isn't a problem anymore and CureII have 100% to proc lilies, it could be better to use it instead.
I never liked to use Cure II or Benefic II except if damages on the tanks are really heavy, probably because, when I began the game, I abused it so much and had no idea what was mp management that i must have been somehow traumatized xD
