Until "Night", Voyager was very stingy with her torpedoes. She only went through 28 of the theoretical supply of 38 in four seasons, before changing everything up. I think she fired 57 photons in the last three seasons.
Funny thing is, "Night" was full of bits with Voyager making preparations for a long sail through the void, and intense boredom during the two months in the dark. It would have been a perfect opportunity for them to show that they had used the time to build new torpedoes, using Seven's Borg technology to bypass their previous technical issues.
That and Chakotay could have finally managed his personnel reviews and kicked up morale by doling out a few extra rank pips, especially to Voyager's long-suffering ensigns (Harry was the most visible, but there were others). Janeway was stingy with promotions, but Janeway was also out of play for two months.
