You guys should add random queue for ranked instead of lobby joining. Right now players can browse and join the same game on purpose, which makes it easy for friends to team up which makes ranked unfair. Ranked is supposed to be competitive and based on skill. You could let players choose the map, mode, and rank range, but then place everyone into a random match with no visible lobbies. Casual can stay the same for friends, but ranked should focus on fairness. If ranked is about individual skill, the matchmaking should reflect that.

Did they change how it works? Automatch used to be just 4 player classic fixed where everyone had hit the “automatch” button. Also does that mean the host can remove u from the automatch? Or does it make u the host?

It will do 6 player but yes still just defaults to classic fixed.
