I don’t know about the majority, but as someone who loves to communicate, whenever my team is gone/busy I find myself joining pubs in matchmaking & I absolutelu despise joining games already in-session.
You’re never sure of teammates’ skill level & you lack the ability of choosing your preferred class.
I don’t know if it would slow or hinder matchmaking, but I would personally like to see more options like in Left 4 Dead:
-Quick Match (any game available)
-Search for Lobby
-Search for Game-In-Progress
Just sayin’. I would love it ️
