This is a fallacy, outside of using iconic monster spells, there is no "play like a bluemage." In FF5 you had to get hit by particular monster spells before you could use that spell, in FF6 it was the same, in FF7 you needed a special materia to recreate a semblance of it, in 8 you had to find special item drops and have quitis absorb it? and use them as limit breaks, in ff9 Quina had to eat a monster, in 10 Kimahri had to absorb it via stabbing them with his spear and like Quitis use them as limit breaks, in 11 ill not speak of it because of spoilers for later in this conversation. 12 didn't exist, 13 didn't exist, 14 yet to be revealed and 15 didn't exist, in tactics you needed to gain certain monster parts i believe.
Lore wise This is where Blue Mage fans don't seem to realize how much of my Vampire idea makes sense here. Blue mages in FF11 which we now know is the past of FF 14, WERE CREATED VIA EXPERIMENTATION / BODY MODIFICATIONS. I cannot emphasize that enough, Blue Magic in this world Isn't a learned thing, it is a symbiosis between a modified humanoid and the absorption of monster essence, Absorption.... Monsters.. In other words YOU BECOME A MONSTER! What is the most iconic Monster that feeds on other creatures? The Freakin VAMPIRE. However we use Soulstones in FF14 So what will likely happen is that you will find the soulstone of a now deceased Blue Mage who imparted all his essence into the stone, and by awakening it you will inherit those traits/abilities, ie become the Blue Mage/Vampire.
They don't have to call Blue Mages vampires in FF14, if it's a continuation of the Lore from 11 they will be vampires regardless. Also Lore wise who would have came up with these vile ideas fo modification other than the void sent who want to take over the mortal world and what better way to do it than to make people start fusing their essences with monster essences, possibly voidsent essence like a certain potential red mage did, oh wait Voidsent will do anything to possess people.
