I've played the UWL about 3 full years now.
It's the funnest events I've ever played. Period.
The multiple roles are just for tabulating points for each position's event/year-end placing.
There's money and good prizes.
They all serve the same purpose on the field except the scout who gets a 10 second head start.
The multiple flag stations and "ownership" points make all the difference.
Team work is highly stressed!
You get nothing for kills.
My team, the Dirtbags ,out of Sacramento have won multiple 10-Man events shooting a grand total of 7-8 cases of paint through an entire event.
