Idea: Class split idea for all jobs

[Reynhart]

I think 30 is the golden point to start off but by then no point in having classes.

Considering class skills go up to level 50, it would still be useful for having a common backbone for multiple jobs. If we keep one job for one class, then, yes, classes are useless now that the cross-class skills are gone.
And, if classes are useless, then, again, the whole armory system is too, since Crystals are enough to lock your job.
