It takes all sorts. Limiting to only the best of the best is no good; that kills all progress and new blood and would be artificial. It'd rapidly become a game of resources, rather than resourcefulness, which is what Robot Wars is all about.

The Overdozer team were complete newcomers to the sport. Their robot was in no way bad, it was just their first build, and built in 5 days at that. I hope they come back and we get to see them evolve!
