It seems like there are indeed some maps that are played more often. I’m not sure if the maps are weighted differently by the game or if maybe more players leave their lobby/game on certain maps, leaving open a spot for me to join.
Overall a pretty balanced rotation though and I think the map pool is decently sized.
Humblebrag: I also tracked my winrate which came out to a cool 84%, with Killhouse and Picadilly as the only mpas with a 100% WR for me. 85% of those games were played solo q.
