Personally I think four teams is a little bit better than having three and since it's an option we might want to go that route. I feel like with just three teams it feels like less of a competition between the different teams and more of one between individual people. Plus that way we don't need to single out one of the people who actually wanted to be a captain and say that they didn't get the job which would stink for them.

The one downside is that each team would just have 5 people then so a team could get in trouble if they have someone who suddenly goes inactive or if the team has too many people focused on a particular event. I guess it's partially up to the leader to make sure the second doesn't happen while they're drafting their team, but there's not too much we can do about the former.
