Outside of abyssea I can live with only cure IV... but inside abyssea with the insane HP, and insane amount of damage taken, Cure IV is embarrisingly outdated to have as a top heal for rdm/sch. Spamming Cure IV in some situations isn't enough, but the biggest problem with Cure IV is the amount of threat it draws. In a lot of situations, you just can't get away with a rdm spamming heals due to this.
