MvM seems like a disaster of a release. I've found servers with only five players but can't loving join because bots are included in the server's player count, usually filling the 6-player limit and most limits. Did you not stop to loving think about things before releasing them, Valve?
Then there's the stuffty GUI system. Why the forget am I able to shoot my weapon with the item server outage dialog up and my (blank) items list? I've had stuff appear partially or wholly off-screen because the GUI system is so bad.
The item server is a piece of stuff. Fix your stuff Valve, you make tons of money but don't even have the ability to run stable item servers. forget you.
