X-Zone, baby! Some of you cats don't dig too much for your ideas, I guess. And since we've already seen BLM throw down a meteor in a trailer, I don't think it's really a "BLMs super want Meteor so I guess we can let those crybabies have it" so much as a "hey look BLMs already have Meteor, or at least Comet or whatever". And Flare as the ultimate BLM spell... what?
That all aside! The rest is just general comments to the thread in general:
Speculating on what would/wouldn't work in 1.0 is ridiculous. 2.0 is going to be a radically different game. It would be like saying stuff that wouldn't work in FF11 wouldn't work in FF14, so we shouldn't have it. Don't expect the limiting game systems or whatever else to still exist, like... we could only have so many abilities in 1.0 so there's NO WAY blah blah could work in 2.0!
Speculating on 2.0 is also ridiculous, in terms of what would/wouldn't work, or how it should work. I suspect that RDM, for example, is not going to be terribly similar to the RDM we saw in FF11. I'm not for/against Time Mage, but I guarantee you that if the FF14 team decides they want to do any particular job, they will be able to think of a way to stylize it in a way that it doesn't ridiculously overlap another job... What would be the point otherwise?
Also, please stop suggesting jobs as classes. Like, Time Mage should be the class and Red Mage should be the job... What? That's like the goof who was saying Thief should turn into Ninja, when ideally all of the jobs should be stylized, and not branching out of each other. That's like saying White Mage should be the class and Paladin should be the job. No thank you!
tl;dr ver.: Speculation is pointless. The dev team should be more than capable of making any classic FF job into a unique and stylized addition to FF14 without significant overlap of other jobs, and any such additions are not likely to fit the mold of your preconceived notions or wish lists of any particular job (BRD should have made that super clear).
