I want the Blue Mage from FF5. AKA the original. My lvl5 Death, my Bad Breath, Dark Spark, 1000 Needles, M-missile etc.

Blue Mage was all about acquiring monster skills and using them to break the game or the traditional battle system.

Oh but this MMO is about balance and scripted encounters so I guess it just wouldn't work at all. I mean you could add it but it probably won't function traditionally. See BLM, SMN, DRK, etc.
