[quote]Grimoire is not skill. It's stubborn determination. It is a reflection of experience.[/quote] But isn't experience (practice) equate to skill, as what you practice at you'll get better at, especially when most raids don't really require skill, but knowing the mechanics (which can be measured in grimoire)? I honestly don't think most raids require skill, but the knowledge of the mechanics. So if I had to pick, I'd say experience is more important than raw skill, especially since it's easier to measure experience (high grimoire) than it is to measure skill (word of mouth).
