I definitely miss this two spells. When I'm not using Fire like a machine gun or Cure, I'm usually casting one of the two, especially when I'm facing large normal heartless (Large Body, Fat Bandit, Defender) on the lower levels. Gravity takes a good chunk of their health. It also works on annoying flying enemies and either brings them down to you or, as in the occasional HB Wyvern hovering just off the ledge and out of reach, throws them down the chasm. Even if they end up respawning with full health again, it's kind of funny to make them fall off the level.
