It is 11:00pm NZ time on a weekday, which is peak time for Oceania.
Here are 2 screenshots of the steam server browser 10 minutes apart:
As you can see, there are no full servers but 2 half full servers and some coop servers.
I find that with this poor matchmaking system currently ingame it consistently puts me in half full servers or even prepares a new server instead of putting me and my 1 other party member into a full game. I find that when I am in a game, not many people join for it to maintain 32 players - which leads to slow and unfun gameplay.
Of course, this is a weekday and the weekends are different as more players keep a server filled. Still, I have seen it put me in half servers like I described even while playing on the weekend.
It's is absolutely 100% clear to me that this matchmaking """feature""" is being beta tested for the console release, as any sane PC player would use the server browser anyway. As such I have a solution for this problem:
Solution
- Enable the server browser
