I've been watching it.
i think the bot teams would have been better if the teams had built their own bot, and truly trained to work together.
Due to the losers-win phenomenon, if the underdog gets to the 2nd round, their bot has fresh parts, whereas the round 1 leader has stressed parts, so they get KO'd early in the 2nd round.
This causes clear under-dogs to win their match, and clearly superior teams to go home early.
Granted, those "superior" teams were all cocky, but they had better coordination between them, and better fighting techniques. They simply lost because of the situation of entering round 2 with stressed, but not broken parts.
