They're not going to make elemental attacks matter again for the players. I also think you either forgot or don't understand red mage in that it was born from both blm and whm and thus why having versions of cure, holy, flare and raise are part of their kit. It's also been their thing since the first game where they can cast both black and white magic with sometimes it costing more but same strength or it costing the same but not the same strength.
