Take it from someone who has had to rehang doors...balance is a good thing.
The Ellison Bronze company is still in operation. They proudly proclaim on their website that they developed the balanced door in 1927:
"In 1927, Edward Ellison, an imaginative engineer from Jamestown, New York, and his brother Oliver, a skilled tool designer with a profound understanding of metallurgy, recognized a need for a better door design. With the advent of taller and more tightly compressed buildings, there arose a need for a door that could more easily overcome external wind pressure and internal stack pressure. Combining their unique skills, the brothers invented the balanced door – an ingenius design that not only solved the pressure issues, but amazed users with its minimal opening force requirements, its reduced leaf projection and its complete elimination of lateral stress."
