As some of you may know, Summoner, if anything, will be dumbed down with the primals going AWOL. In order to save the endangered classic, I wish to suggest a new form of summoning.
Instead of the Summoner summoning a separate entity they would envoke the essence of the primal into themselves. This would cause the Summoner to sprout horns, claws, and a tail if Ifrit is envoked. The summoner would turn red and glow with lit embers.
Each primal would have a set attribute; Ifrit: STR, Garuda: Int, Titan: Vit, etc. The sub primals, like moogle, would be a mixture. Doing this would allow a summoner to specialize in a single primal, yet they would be able to envoke them all after each condition has been met.
That being said, I would suggest a separate magic class for the Summoner Job with CON/THM as subs.
