Well, it happens, everybody has his first few games, and not all are good at first. Though, it is pretty frustrating. I had a similar experience in a game. I think it was a a 2v2, not sure now. It was on Prison anyway. My teammate was playing a Rook. And apparently he took Rook's awesomeness pretty seriously, as he fearlessly charged against enemies regardless of health, even when alone against two. And died. A lot. And when he didn't find enemy demigods, he just went straight for their towers and stayed on them until, yes, he died.
I tried asking him few times what is he doing. No answer. I played as QoT and tried shielding him.. well, shield has, what, 7 seconds cooldown and I only have so much mana. He died more. Sometimes he managed to Hammer Slam before dying, it was a happy moment every for me every time. Eeh.. anyway, by the end of the game Rook had more than 20 deaths, and it wasn't a long game. He actually managed to destroy few of their towers, too.
The frustrating part was about the first 10 times Rook died or so. After that, luckily the other team wasn't totally mute, so it wasn't all that bad. And it certainly was a challenge. Too bad we lost, dunno why
