What he's saying is that random team 3v3s and 4v4s the random teammates you get have a much bigger impact than the balance. You could play the game perfectly and you'd still lose if one or two of your teammates are terrible.
It's very hard to identify balance issues without everything else being fairly consistent, and large teamgames with random players are the most inconsistent modes in the game.
you can be the best player...when your teammate in 2v2 fails hard...u will lose. and even in 2v2 u can abuse cheese with some faction/ commanders.
but katitof have such a little play experience overall : no teamgames above 2v2. only 30-40 games with brits...playing only with super strong teammates. he isnt in the position to tell us something about the game like a teacher. (i think he sees himself in this position.)
he never played a seroius amount from games. and much less as random. His look on this game is from a vacuum.
