Red mage was a hybrid between Black (nuker) and White (healer) and a bit of their own unique magic as well. They were sort of like Druids, except without the focus on nature. Their emphasis was being a sturdier all-around caster that could nuke well, heal well, melee okay, but not be the master of any of them.
Blood mage is VERY different. It's slated to be a healing class, hands down. And deals with blood. Just because blood is red doesn't mean that a red mage is a bloody mage
