THAT BEING SAID, I am comparing the king of magic DPS to Blue Mage AND under the assumption that the Black Mage is going to constantly be in Astral Fire, which isn't accurate. That being said, the downtime in Astral Ice still doesn't let Blue Mage catch up that much, with the main strike being the lack of Firestarter procs. But if Firestarter procs at least three times during a thirty second period then the Black Mage still has the advantage, even more so under the consideration that the second usage of the Primal Abilities won't be under Peculiar light.

And again, in the realm of AoE Blue Mage is absolutely king. No damage drop off on spammable and decently powerful AoE, the ability to perform a one two punch on normal mobs with a base potency of 310 WHILE RESTRAINING SAID MOBS, TWO AoE DoTs with one still being a 90 potency attack as well, THREE instant cast high damage AoE attacks with one not suffering from damage falloff, THE ABILITY TO BEEF UP ANY OF THESE EXCEPT THE PRIMALS BY 50%, an AoE paralyze power down poison etc...

And in all due fairness again, Black Mage. If I had compared Blue Mage to Red Mage the end result would be different. Not to mention that Blue Mage has a good deal of support going for it as well. In group content Blue Mage is going to have a lot to offer. Its damage is just a bit lower then it probably needs to be at current.
