This probably isn't the thread for this, but...

Just throwing it out there. If class-centric equipment had some enhancers to cross-class abilities. Heavy armor for Gladiators and Marauders that may enhance an ability outside of their respective classes. Where the job continues to accentuate the exclusives and further the role.

As it stands... well in any game really, I think folks have considered acceptable efficiency. The way that they stack jobs for certain fights type of efficiency. Anything outside that efficiency is generally frowned or not tolerated. With the community heading toward this route of limited acceptable choices, it makes me think that adding new classes/jobs will be a wasted thing.
