As far as I know in past FF games red mages just cast the same black or white magic as the other mages, just with a more limited repertoire. I imagine they added the "Ver-" prefix to differentiate the spells since RDM's spells are actually nothing like their BLM or WHM counterparts in this game.
I plan to main RDM, and look forward to it, but this rendition actually isn't anything like previous incarnations. It's supposed to be a hybrid mage but this job might as well just cast "Red magic" because all of their spells are unique in function except for Vercure and Veraise
Well, starting with FFV and its doublecast command, Red Mages have emphasized using a large number of spells over powerful spells. This extended to FFXI, where they had access to chainspell, and Bravely Default, where they were the masters of BP gain (which meant more actions overall).
They do have a history of having a unique take on their spell-list as well. In FFXI, unlike the Black Mage which focused on high-power nukes, the Red Mage used DoTs and debuffs. It had a few unique spells, namely the Bio and Dia lines of DoTs, and the En- and Bar- elemental spells. The En- spells (such as Enaero and Enfire) were buffs the Red Mage cast on itself to imbue its physical attacks with elemental damage. They are in FFXIV as spells the Beast tribes use. The Bar- spells (such as Barblizzard or Barthunder) reduced elemental damage.
So rapidly chaining together attack spells and having elemental spells with special suffixes both have precedent in the franchise for Red Mages.
