Well, it hits two groups the hardest. There's the people like Water, Syzygy, etc., who are the top F2P players. Losing all their ranks is a pretty shitty feeling. Then there's the people who got 200m skills in the past who decide to drop their membership because they don't play anymore. They lose that once-permanent rank. If the number one ranked player in a skill becomes F2P for a day, they get put at the bottom of the 200m list when they renew.
