James, the guys of Hypnodisk had a very solid reason, the team of Wheely Big Cheese had theirs, and so did the people of Razer. All these have been discussed ad nauseam on the Robot Wars forum.
But when Razer fans keep on yelling and yelling that their god would win everything people do tend to become a tiny little bit annoyed about that. So it is not the team we snarl at, but the brainless idiots who call themselves fans.
