Well, nothing really changed for teamgames. I still have to restart the game all the time, it get stuck while searching a lot and you have to restart over and over again.
It also happens quite a lot, that 3 or 4 are on the same side and its not a 2v2. If you interested, i made some screenshots in Steam (steamname - Wolf_Kocmoc).

The ladder seems to work, people say the coward things also work mostly.
Avatar tree seems to work now.
Summary, ladder got better, yes. But the other problems are more or less about the same.

The question is, what is CA doing about the balance problems?
Whats with the 22k games?
Whats with the bugged retainer?
Whats with the bugged maps?
Whats with the terrible moral?
Whats done about the strong effect of general?
Whats done about the artillery?
....
