The ''Would you like to switch teams'' prompt will not accour, as the imbalance is only a 1 player difference. Heres an example: Your friend is on red, on a game were blue has 11 players, and red has 12. The game is waiting for someone to leave, and the game to be imbalanbced in the team your friend is not on's favor. Using this information I can also explain why when you try to join your friends match, it takes forever. Valve implemented quickplay to make sure you weren't alone. Before MYM, quickplay would simply put you in a match regardless of how many people were there. This is why having more friends in your party takes less time to que a match, as more of the reuired player count is filled up.

Once the game gathers up enough players, then it will connect you to the server. It will not connect you though, as it is waiting for more players to also get said map. When you press the butten to que you for a match, the game wil find you a map in about 3 to 4 seconds.

Today, we still have to wait for around 30 seconds, and by observing how players would join and leave servers, I have found how it works. Later we were proved wrong as matchmaking times shortened, and we started to care less. For the first few days, putting you in a match would take up to an entire hour, and everyone thought that this was how it was going to be.

Before MYM, quickplay worked by randomly picking a server that fell under your paramaters. The reason casual matchmaking takes so long to put you in a match is suprisngly more simple than it seems.
