Yes, usually. A higher grimoire score means more experience. Which usually translates to better pve skill. I know this isn't 100% accurate!!! It's the same thing with medal score. If I need to judge someone's skill from a glance at their stats higher medal score people are usually ([b]not 100% of the time[/b]) are better. This is because if you have a lot of medal score, ie: in the millions, you obviously play pvp a lot. Then if you play pvp a lot you must probably enjoy it. And you enjoy it because you are a good player and do well in games.
