I believe op is pointing out that your chances of being with a more skilled player increases with a high grimoire. And in my own personal experience it rings true. That being said I have played with folks with a high grimoire that were very mediocre. Also I have played with low grimoire people and they were great. So there are exceptions to the rule. Edit. I would like to add that I'm not in agreement with 4600+ mainly because the pvp aspect of it but 4100 or more at least let's me know you have time invested in the game and should know what you are doing.
