As someone who plays RDM, this idea gets a big NOPE from me. It's not that it's inherently bad so much as it's just another job that would overshadow red mage and make it even more irrelevant. Bring a job like that in and now RDM really would be nothing but its raise and people would still use it as an excuse to keep the job down. I agree with the poster above me, just give RDM more options for melee attacks. That will never happen of course because square is full of cowards and devoid of any and all creative energy but yeah it would be nice.
