Do defensive, low scoring tactics work?

I apologize in advance if this was brought up before, but I haven't found anything on the topic.

Say you had a robot without an arm. Strategically, you could just take tetras from the human player and depositing them into the goal and repeating. Also, I guess you could play some sort of defense, possibly going as far as to remove tetras from the opponent’s goal. You could also get some tetras onto the field if requested. You would get back to the line for the bonus 10 pts. if applicable.

Now my question is, seeing as this strategy only nets a few points, would you call this 'bot valuable to the alliance? I sort of feel that in order to be liked by your alliance partners you have to get points and be offensive. Would you not pick a team with our strategy in the playoffs? Are we worth anything to other teams - do we have any value?

Basically, in the past have the successful teams been the ones with gung-ho offensive tactics that get many points, or can the little guys succeed as well, even though they may not contribute as many points in the end?

Do you need an arm to make a difference in the match? Do defensive, low scoring tactics work? What makes a "winning robot"? What are your thoughts?
