Well they weren't the true winners because they didn't win, but they did an amazing job given what they had to work with... and they had a really nice, unorthodox team composition. I think it's quite telling that top 2 went with something rather new, while third team took a very non-Hinkley comp and made it work. Also congroo to Cheeki for that sneaker play, can't wait to see the youtube vids.
By the way, there's nothing wrong with gangs fielding 2-3 teams imo, it's not like they're guaranteed to win or they increase their odds because 1 person can't fight on 2 teams. Besides, both teams could clash on round #1 and from a gang perspective it's just a waste of 25k on a pre-scheduled Hinkley match. ARWH and TLS both fielded 2 teams and didn't make it to the top three. TLA fielded only 1 team and they probably had 10 people sitting it out on the bench. I actually didn't like the 2 team limit, I think it shouldn't be present on the next event because it's basically punishing players who are in large gangs. You still need the skill to win and the implants are a personal thingie, not a gang property - if one of the winners decided to quit his gang, his implants would go with him.
If you really have to impose some limitation on multiple teams from one gang, simply increase the buy-in cost for subsequent teams:
Team #1 25,000 caps
Team #2 50,000 caps
Team #3 75,000 caps
etc.
