I think 3 on 3 is probably too complex for its own good. I think the thinking was that we will get more folks playing more rounds. Partly that worked but partly it didn't. It worked in the regionals in that more matches were given, but it did not seem to work for the Championships in that only 7 matches were played per team.
In my opinion, 7 is to few to sort things out. I am not sure what the right number is but 7 with 84 teams was too low.
One think I DID like is that the entire alliance played every match not just at least once per round.
Read here for proposal for tournament structure that keeps some of the things I like and gets rid of some of the things I don't.
