@OP: Those spells were part of a crapton of other abilities that existed in the game before the class revampt that took place after Yoshida was given control over the game.

I wouldn't take those as hints to RDM but rather hints on combat systems and the original armoury system. If you want to see what the original armoury could have achieved, you need not look further than The Secret World, a game that uses the exact same system but with the element of decks. Decks are pretty much class names your character gets based on abilities they set in their action bars (like if you want to be labeled a witch hunter you needed specific abilities set and you'd earn the label as well as a small bonus to the abilities involved).

I have a feeling Tanaka's FFXIV was aiming at something similar. Set certain abilities/spells in your action bar and you'd be a Black Mage, or a White Mage and so on. It would make sense given the abilities in-game as well as the sheer number of jobs in the FF IP, and would also explain why the base classes were not named after the jobs to begin with.
