Well, obviously the future of The Year of Hell was going to be avoided, and I didn't really expect Kes's life would've worked out just like Before & After. Tom may have gotten together with B'lanna anyways, and I did like them as a couple.
Kes could've been the focus of the Doctor's affections instead of Seven, or Kes could've stayed single except for the random boyfriend of the week that people on Star Trek get.
It's all subjective though, as I never found Kes boring. Her stories were sometimes not as good as others, but that's true for everyone.
