I said about a million times now, Valve changed their matchmaking system a couple months back and now the entire system fails epicly. 8 people at WCU could be in the same lobby and select “Best Available Dedicated” and it would pick a server on the west coast with a 300 ping instead of one on campus with a 20 ping. Better than that, I’ve been in lobbys where “Official Dedicated” was selected and it dumped us into a heavily modded server where the lobby lead was admin and his whole team speedhacked into the saferoom.
Don’t bother complaining to valve about any of that. Their response to poor matchmaking is to reinstall Steam and they never replied to the complaint about the official dedicated option selecting a modded server. IMO they don’t know wtf their system is doing.
If the L4D2 servers aren’t showing it’s probably because domo didn’t turn the LAN servers off and most of the them are crashing/restarting a couple times per minute. Until they get turned off the servers going to be about as stable as a 3 legged dog on ice skates.
