Classes are jobs. Different words which describe the same idea. Is that too incomprehensible for some people?

I'd rather see a Black Mage, who casts black magic and not a Smukeltigloopagloppinwimwang who has no defined role.

On the topic of "Openness": the skill sets define the openness not the name of the classes.

I am all for SE swapping the skills around to make the jobs more specific or play more like their original FF series counterparts. We all play FF for our own reasons, but the majority of FF players I know love FF for its staple consistencies.

If you don't like that then go play another game dude.
