I'd have to agree with most of the points that have already been made: I'm waiting for the hype to die down, then I'll unlock the job and formulate my own opinion.
Right now, there isn't enough concrete information that we can even base an opinion on. I was pleasantly surprised to find a Blue Mage Job Forum added here, although the joke threads "ZOMG I hav teh BLue Mage!!11!1oneone!1" have gotten very tired, very quickly. (Not to mention, it's confusing the hell out of some of our lesser-informed peers)
Blue Mage (or the equivalent in other FF games) has always fascinated me, despite that so many people I've known have always been like: "Blue Mage in FFV is weak, Strago sucks in FFVI, Enemy Skill Materia is stupid in FFVII, etc. etc." I've always spent the extra time to find all the Blue Magic spells and make those characters some of the most formidable and versatile fighters in their respective games.
As much as I welcome the introduction of Blue Mage (finally!) into the game, I'm also bracing for the bandwagon to come storming through. Most people will drop it after level 10, or Valkurm or even Qufim I'm sure... but that can be said of most jobs really. To be painfully blunt, I have a sense that Blue Mage will require far more trial-and-error, research and work than most FFXI players will want to devote to it anyway. This will be true especially in the beginning when no formal strategies for leveling/skilling Blue Mage have been made public. (Naturally, the "OMGWTFBBQCHIKEN!!1! SE is stoopid, BLue Mage suxx, blah, blah, blah" threads will follow)
I imagine it'll be a lot like the NPC Fellowship quest that was introduced; it will be a novelty to most and only those who are truly interested will see it through to the end. Also like the NPC quest, I'm going to wait for mine... some people I know waited 8 friggin hours on lines at Eldieme and Ghelsba to fight the required mobs on the first day. I waited a couple days and did mine in maybe 1 hour flat, counting travel time. Fast forward to today, my NPC is level 41 and more than half the people I saw at the NPC quest sites back then haven't touched their NPCs in over a month now. XD
To the point of this thread, I plan to pick up Blue Mage on a serious level, but the only way I'll truly know for sure is when I try it out for myself when the expansion is released. ^_^ Unless SE severely f*cks this job up, I would love to be one of the Blue Mage "pioneers" on my server of Ifrit. :D
