I'm disappointed that classes will only have 1 job, but it's ok for some of the classes. For examples when I started GLA I thought I'd be a DPS swordsman, turned out GLA isn't quite that. So it makes sense for it to become PLD and nothing else, I guess. But as it's been said, CON and THM are so hybrid they can only do 2 things:

1. Recontrust them from bottom to top. This will inevitable cause a lot of rage, I think everyone can see it coming.
2. Give 2 jobs to THM and CON. For example, WHM and BLM for CON, and I don't know, maybe RDM and DRK for THM? Giving WHM and BLM to CON makes sense. RDM makes sense for THM but I can't really think of another job for it that isn't far fetched to some extent. DRK is, because THM is a mage and DRK is a fighter. TIM(?) is, because nothing in the lore indicates that THM has any control over time. So yeah.

Anyway I think option number 2 would be much better, and I was actually hoping they'd give 2 jobs for each class.

Something like this:

GLA: PLD or ??? (NIN? lol)
PGL: MNK or THF
MRD: WAR or ??? (DRK?)
LNC: DRG or ??? (SAM?)
ARC: RNG or MSK/COR
CON: BLM or WHM
THM: RDM or ??? (TIM? DRK?)
