When will we get info on class changes?

i think CON will get blackmage, as you point out blackmage always has elemental nukes. sure they get other magic but always have elemental nukes. but this argument about jobs fitting lore, i have to look at paladin, and think ul'dah gladiators don't seem like knights with godly connections, nor do marauder. but i still put CON as blackmage

It all depends on how they continue lore, I suppose. I don't think you can really say that class=job(ARC=BRD?). The two aren't the same thing, nor are they meant to be. Same goes with GLA/PLD, they aren't really the same thing, but they will be related in some way. I'm sure there will be some kind of nobility quest line that guides you down the path to becoming a PLD, and explains how this comes about.
