I don't like that kind of players, you may be that one that blame on his team mate.
50% wins playing well as you say is a low ratio. I am not a pro and I have >60% of my wins in 2v2 AT with many different players that aren't pro players. I don't blame at them, sometimes one of the team player have to dictate the orders, if you are better than your team mate, it's your fault for not managing the game correctly.
I played 2v2 random as well and my ratio is >60% wins. I don't play random for months, that explain my rank 1000 but still the ratio is so important.
I like your attitude to study the data in coh stats and trying to improve but in team games you need to improve your team play. If you don't like that you better go on 1v1 in where only your skill matters.
He reminds me of a guy called Huricane. If he loses a squad he will find a way to blame you. It really is a learn to play issue. Plenty of times I've had rather poor team mates and on some occasions I play poorly which I admit. But as you can see from my playercard I would consider myself one of the better OKW players out there, in terms of 2 vs 2's anyway.
I was on the UK team for nations cup and as we were about to play the Netherlands the tournament was cancelled. If you're looking for help and advice SuperJew, you might have more luck if you came across as less arrogant and stop blaming your teammates, look to your own mistakes before criticizing others, or else you'll just look like a massive knob.
