I can see why he retired. He was so good that he got banned for too many pub servers, lol. I can agree that some of his shots might of been a wall hack, because there was no way that he knew that they were behind wall or corner. But his reflexes are just off the charts man!
I remember watching the series as well. The show was called Avatar: The Last Airbender, which doesn't make sense to me when the movie Avatar came out. I got sort of confused from that, lol.
