There were also some other tricks DS9 pulled; The size of ships got scaled down from TNG.
The average Klingon Bird of Prey used to be the same size as the Enterprise, but in DS9, they were size shrunk to about half its size.
I think one reason was to make battle scenes look more exciting from the outside. In TNG, ship battles used to be real slow and clunky with the shield bubbles and all.
Compare Yesterday's Enterprise to WOTW OR SOA, and you can see the difference.
But I think TNG had the best bridge suspense battle scenes.
