I'm not certain that Great Hero is actually greater in terms of power and everything...but it might have additional abilities or something.

You say that you can't think of it as a more powerful thing than Hero...but keep in mind that Rou defeated the Red Bear when he was a Hobgoblin and they mentioned that it would easily be able to take down a normal Ogre (or maybe even multiples) IIRC.

Basically, there's already a precadence for a person's full strength to not just be tied to their jobs/species.

You have to take into account things like Arts, Job proficiencies, secondary skills, blessings, etc. for humans...and for monsters you have to take into account abilities, general proficiencies (that are expanded upon w/Rou's training and everything), general stats, and other such things.

There's more than just the "Job" factor. There's also the possibility that he's not just a Hero, but also has a bunch of other jobs that elevate him to a higher level than someone that's "just" a Great Hero thanks to him being proficient in using them in combat and whatnot. ^^
