This discussion got me thinking that it would be cool to see the new jobs having more utility to make up the possible lack of cross-class. I'm seeing two scenarios.

1. Even though the new jobs will not be a class -> job thing, it'll still have a cross class function, just for the sake of utility.

2. The jobs will have their own animations, but have the same effect as a similar class. e.g. Astrologian will have a skill similar to Cleric Stance, but with their own animation relating to their job. And with that, we may be able to gain more unique skills down the line of the job from lv.1 to be up to par with a job that has cross-class skills.

Just my speculation for the morning.
