I'm not claiming my suggestions are good. I even said as much when I suggested them. But the terms "Adventurer" and "Warrior of Light" are actual nomenclature used within this game and they're delineated pretty clearly by time. You're a lowly everyday Adventurer when you start out. You become known as the Warrior of Light by the end of ARR. Therefore ARR = Adventurer. Post-ARR = Warrior of Light.

Capstone is not a term that is used in this game. It's a term that is used in one other game that is a few months old and doesn't mean anything here. We have not adopted this term in the larger vernacular of video games.
