Yes so the game has never had a healthy enough population to support true subrank matchmaking. And asubrank being 100 SR points is pretty wide actually, I’m not even asking for a lot. M1 to M1 is still wide yet we can’t even do that.
Groups is simple. Don’t allow groups for comp. It’s anticompetitive to mix groups with solo players. Blizzard allowing grouping in GM is a joke for competitiveness and further shows how clueless they are when it comes to making a competitive lobby
Like I get where you’re coming from but your “example” of grouping being something that makes this “not working” - just kind of shows you have the mindset that Blizzard has that is trapping the game in mediocrity. Grouping is a trash idea for competition in the first place, not something we need to play around
Queue-times is just analogous with player population.
