When playing a team game it is some times difficult to miss the smaller and the bigger picture. The idea is to let somebody be part of the team whitout having any controls.
The guy can then coach the team, spot snipes and drops and he can think of a overal strategy whitout the pressure of managing his own army.
The lobby need three observer boxes, two for the observers of both teams and one for the neutral observer.
Just an idea..
Cheers
