Quickplay is dead, this is a good thing.

Many users enjoyed quickplay, but there is one thing that made it a horrible way to join a TF2 server.

By default, quickplay would set you to join a server with random crits enabled. For a lot of people, they said that this was the sole reason that they would not turn off random crits. It would affect the popularity of their server and they would not be able to upkeep their server.

The times have changed now. There is no longer any such thing as quickplay. From the updates succeeding the MyM update, it doesn't appear that they have any agenda to add it back in. This means that the community servers that are highly populated today will not be affected by the turning off of random crits.

That's right, now people are just as likely to join a server if it has crits disabled as opposed to enabled. This group strives to start a movement: turn off random crits. Server operators have this entirely in their control.
