Nope. I'm a day 1 casual and would call myself above average. Not the best, but definitely better than a good handful of people I've come into contact with. I base this off DPS, kills per raid/strike, and K/Dr. My grimoire is extremely low compared to basically all day 1 players but I am limited on play time with a demanding job and other life stuff. Never had time to collect ghosts and all that other stuff.
