any 3v3 matches people start to drop left and right from.
I just left a post entitled "People... for the love of Christ." In that post I stated this very problem, i.e. this game obviously has connectivity issues and everyone knows it. As such, you seriously increase the odds of "a player has left the game" when you have these 3v3, 4v4, 5v5, and 6v6 matches. Why? Simply because you are contending with more people.
To lower the odds of "a player has left the game" and increase the odds of actually being able to get a game online with other people, there should be many more 2v2 matches, and far fewer of these 3v3, 4v4, 5v5, etc.
After I left this post, I was flamed like 10 times, and then the post was apparently deleted (thank God) as I haven't been able to locate it since. But yeah, my advice is that most people should try to host as small of a game as they can possibly host.
