Temper has nothing to do with the Manifesto or Red Mage's role as an enhancer. It's a melee buff, because people wanted melee buffs. It is not expected to make Red Mage a viable frontline option, frankly nothing will ever accomplish this. But all of the reasonable RdMelee proponents here have been asking for a simply buff regardless of whether it would change the job's status or not, and that is what they got.
