I feel the need to bring up something that was stated on the first page:

What's preventing you from scoring on your own robot? You could have the payload specialist keep a watch for a totally lopsided score, and have him/her switch targets to your own robot..You could even make your trailer a sitting duck....

So I think this rule forces you to be more creative, and that outwieghs the disadvantages to better teams.
