I have 4205 grim score, my group has completed Kings Fall in ~40mins in the past and average ~1 hour completions. I don't care about increasing my grimore score. I used to believe it meant something, but it really doesn't. If you play a game alot you understand the mechanics, and how to fight an opponent. This does make you more skilled at the game, but this doesn't mean that your more skilled at the game the someone with a 2k grim score. Some people are just naturally more skilled at games then other people.
