There's no article, the proof is that it's plain to see, classes have lower stats than jobs so no matter what you do you'll always be weaker as a class than a job. Anywhere where classes have had even a niche use have been stamped out by the devs (marauder was actually better than warrior in pvp at one point but they nerfed classes by giving jobs a 10% damage boost over classes in pvp to prevent that). Past HW only jobs got new abilities, classes got nothing past level 50 and the new jobs didn't even have classes, they just start as a job. They even took LB3 away from classes just to hit home that classes are worse than jobs. SE wants you to get the class to 30 get your job stone, equip it, making your class inferior in every way, and hope you forget the class was ever there.
