Not many people , they have a dscord groups though to organize games because it’s rare to see multiple games up, and even when there is chaos games they tend to fill quick or be private

Classic is a great time though, I’ve played for seasons1-3 , got on front page of ladder every season, including #1. Leveling is one hell of a grind on classic though, getting to 99 on expansion is easier than getting to 94 on classic, number of runs wise
