They kept a count of Torpedoes until season 5.
Voyager actually became more and more character focused as it went on.
You make it sound like she came on to Voyager and turned it into an action show, but she was one of Voyagers creators, and showrunner for the first 3/4 seasons. And season 3's 'Macrocosm' is hardly an example of the overall tone of the show. Nor is it the only series to have the occasional action/suspense episode. Remember Jean Luc McCain? If I had to guess how many times Janeway picked up a phaser rifle throughout Voyager's 170 episodes, I bet it would be about 3. The only other time I can think of off the top of my head, was very briefly in "Night" when the ship was boarded with the power out.When she became showrunner of VOY, she had Janeway in a tank top, backpack and armed with a phaser rifle, fighting large macroviruses.
