Want viewers want is quality entertainment, whether that be political (The West Wing), Mystery, Adventure etc..
Also Star Trek isn't just about 'Trekking to strange new worlds'.
So what is it about??? You saying Star Trek has actually become greater from Gene Roddenberry's concept of humans growing by exploration, adventure and learning of the universe to the repeated use of spaceships shooting purple and green alien space ships week in week out?

As for why the Klingon's don't build smaller combat vessels like the Defiant, or why theres can't compete.
1.>Federation ships have better shields.
2.>They don't have the technology to do so.
3.>Lack of neccessary resources (i.e materials needed to fabricate those parts are scarce in the regions they control)
I'm sure I could come up with others if I gave it some more thought
So the USS Voyager, which could beat ships which easily outclassed it wasn't to make it look cool?
Are you 15 years old or something? The point is they could have used *anything* as the hero ship to beat the alien bad guys in each episode, and come up with some silly technical "canon" reason why it could.
And there lies the problem ..... you can't just make up some theory like "Federation ships have better shields" to cover up the why a small Federation ship is mysteriously more dangerous than any larger ship in the ST universe, especially when the Klingon's who are a race who thrive on war been making small war ships since the TMP era.
So what this simply boils down to is the Defiant wins and beats anything because the ST DS9 producers wanted a hero ship that they think looks cool. Stuff that shoots things appeals to boys who aren't interested in sci-fi, they just want to see things get blown up.
