I, personally, would like to see another job that does blunt damage. If I were to design red mage, I would make it a DPS job that uses a 1H mace for blunt damage. I know a mace is not iconic to the red mage job but they have used them before. I envision it wearing scale armor similar to dragoon as it would be a melee DPS. Optionally, it can equip paladin shields.

Play style would include generating combo points on an enemy (similar to WoW's rogue) and using said combo points to cast AOE spells (black and white), which can be used in conjunction with Double Cast, an ability with a 60s cooldown. It would also have access to enspell, barspell, and enspike abilities. Ideally, I would also like to give them an in-battle resurrection ability.

However, the problem then comes in selecting the main stat for this class. I would select it a STR class but its spells could be percentage based as opposed to potency based, thereby eliminating the need for focusing on INT or MND.
