I'd like to think it's for rewarding the skillful players.

For our World of Chaos trilogy, I was going to implement a medal system where boss medal quality is determined by how many hits you took. Platinum means you defeated the boss without taking any hits, Gold means you only took one hit, Silver is less than or equal to 3 hits, Bronze less than or equal to 5 hits, and Rusty for anything more. This is to encourage players to play as skillfully as possible, and tank less.

I imagine the grading system in this game is to function the same way. You load your previous save file and try as many times as you want, if you really want to earn the highest title. But for those who don't want the bragging rights for their hard work, they'll just have to settle for their lower-end medals.

The boss medals are nothing more than for show.
