No More Classes?

[Wintersandman]

I highly doubt that's how it'll happen. I honestly don't even think we'll have a Job Crystal with these classes as unequipping a Job Crystal turned you into the Previous Class, you can't unequip the Job Crystal as these new Jobs as they have no class to break back down to. So, either we'll have a Crystal we can't unequip, or we won't have one at all.

As for balancing your idea of DRK/THM and DRK/MRD, FF14 as a whole is a lot more balanced and has specific roles for each Class that FFXI didn't have. Doing that would go against that idea

While I agree with you, the Job Crystal is what changes the specific roles. For examble take the Arcanist Jobs, Arcanist by itself is a dps class, attach a SCH job crystal and now you're a healer. So if you are a THM for example and you equip the DK crystal, you will become a tank. The crystal itself can have a base HP that it starts off with etc. It's not entirely a stretch.

Without the crystal they are mere classes rather than a job. To me the crystal is what separates the two.

It's all hypothetical and the expansion will define it all.
