That's not laziness, it's a difference in approach, Astral. Reven usually hands off characters from the quest and leaves their roleplay and similar elements to the players. Putting together another knight isn't a long task, generally speaking. But there's no guarantee the assembled knight will match the image the player has in mind.
That's true, actually. If the character was created by the player, I won't add anything of my own or roleplay them myself.
By the way, I have no idea how Reven's status application chance works. He never specifies it anywhere, probably since some ancient expeditions. So as for the chance, no clue.
Whoever roleplayed their willpower better, that's who gets the credit.
