Temper should have been a sphere effect. That would give red mages a reason to be on the front line with the melee. Once they're up there they might as well pull out a sword. Obviously red mage melee can never be buffed enough to make it a worthwhile DD or dedicated DD jobs would rightfully call foul, so if SE is serious about RDM becoming situationally useful as a frontliner they need go give a different reason for them to be there. Sphere could have been it.
