Blue mage magical spells have not kept up with the recent changes to elemental magic. The magical attack power is not in line with the massive MP cost, and more significantly, the extremely long casting time and recast time.
This is painfully apparent in an event like Skirmish, where a blu & blm are guarding the tent using magical spells. Virtually any blu magical spell that is used (thermal pulse, charged whisker, leafstorm), the blm can easily cast 2-3 AoE spells before the blu nuke even gets off.
Please examine the extremely long cast and re-cast time of blue mage magical spells. I'm even more concerned now because it appears that the majority (6 out of 11) of the new blue spells we are getting in the November update are magical in nature.
Blue mage magical spells pay a penalty in four areas:
1) Extremely long cast time
2) Long recast time
3) Lower magic attack power compared to other magic attacks from BLM
4) Extremely high MP cost
It seems like one or more of these areas need to be reduced. (I would be happy with cutting the long cast time in 1/3 personally .. ).
