Same thing here.
As for the whole "Wahh, can't use Sentinelskinvigoratewind anymore", the whole point of the job system is to specialize players so they excel on a certain role while needing more party support due to not being as self sufficient as before. So, yeah, a BLM might not be able to use sentinel / stoneskin on Hellfire, but will be dealing more damage and white mages / paladins are better prepared to protect and heal a party after this kind of attack - so you won't be needing it anyways if all goes well.
Not to mention that, as others mentioned, you can still use classes and I'm pretty sure there will still be certain strategies and content where people will indeed prefer to go as classes.
