My opinion has not changed in the 20 minutes since writing it. You can be carried through team based game modes, which are all of them barring Rumble, so you don't have to be skilled to grab those points. The Rumble Grimoire is the only one requiring any sort of "skill" to get. Need raid Grimoire, you can be carried! Need trials Grimoire, you can be carried! You can say you have a lot of experience in the game when you have a high Grimoire, but you might be an awful player when it comes to skill level.
