I think if only top 10 were taken to finals, it would make the whole event more exciting. It would make it so almost every single team competing you WANT to see. No sitting down and wasting your time with teams that barely scratched through in 19th place that have no real shot at winning. No offence to anyone, I just think the majority of spectators at Worlds, especially day 2, are there to see the top teams, the big names, not the small senior team that looked like it was thrown together 3 days before hand that somehow managed to hit and make it into finals in last place. (I know this isn't always the case, Rockstar Beatles were 17th day 1 in 2011)
