What I think they need to do is just make classes be able to equip a variety of weapons that are semi-related to the class, and have WS's swap according to the variety of weapon.
Then all that's left is to keep Jobs strictly weapon-locked, for role fulfillment.
For example, a Gladiator un-equips his shield (which is currently pointless to do. D, maybe gains an attack buff, loses all of his shield skills, and in replace gets DD focused WS's, or maybe equips a dagger and gains DPS WS's.
This would give variety to classes while opening up possibilities of new jobs, and also allowing jobs to be very different from classes.
All in all, classes have the ability to be very robust, and should stay solely because of the potential they could bring with a few changes. I often feel the reason classes are here is lost on some people, originally they where meant to be more of a "design your own class" feel, which is what they should expand upon. Make classes be almost limitless, able to overcome a variety of situations, yet hampered in terms of role definition, giving better stats to jobs for obvious reasons.

TL;DR: Classes should be more "Jack of all trades" with lower stats than Jobs.
Jobs should be tailored for a more structured play style.
Also, speaking of classes and jobs + polls, didn't yoshi say that the battle poll results would be revealed with the patch notes or am I mistaken?
