Lol I have a 2725 grimoire score but would most likely wreck you in pvp. I go flawless 3 times a week usually within the first 2-3 hours of release it will be done on all chars. Grimoire score has more to do with the grind of the game. Most cards will be for killing a certain amount of enemies, so if you think aiming and shooting at AI bots is skill then hats off to you. I have only found around 6-7 ghosts so the score is purely from doing what I like doing which it should be. Stop judging on people's score judge them on their skill.
