The worst kind of newbs

I was in a 2v2 and my teammate was a level 7. He was clearly a newb and for the most part I accepted that since I had scouted and had come to the conclusion that I could win easy with him just tagging along. But then just as we are about to attack,(Im Hu, he is Hu) disaster strikes. On the way to our meeting spot he spots the enemy team creeping together and decides to pay them a visit, I demand that he deter from them and meet up with me but he decides that a mad dash at the enemy with zero chance of success is a better idea, turns out it was little short of a massacre. I came but it was to late by the time I had arrived. His casters had all been killed off and his un-upgraded knights had been slaughtered. So I say, WTF?? Why do you play 2v2 if you suck?! He then denies he is a newb and demands that it was my fault that his army is dead because I did not come fast enough. I hate newbs like this that take it upon themselves to screw over good players.
So if you suck at ladder and are a custom newb in wc3tft plz, think twice before you play ladder, go back to custom and play your little tower games.
