Possible Fiora Rework changes?

After playing fiora several times (and this is bots, so it's purely comments about mechanics, I'm not whining cause i got no kills or i lost), I had a few ideas to make the new Fiora at least slightly more playable in live. Her one on one and laning phase is decent, but not awesome, however her team fight is so outrageously bad that i feel its worth mentioning. As someone who is supposed to be fairly damage heavy, every time she enters a team fight she gets picked off almost immediately , because she can block for a second and then it doesn't come up for another 20. Her ult is nearly impossible to land if they have any cc on their team whatsoever. She is heavily single target but is incapable of killing someone without dying first. she has no real role and isnt that useful.

Now, A thought I had was to make it so her lunge has no cooldown if she strikes a vital with it (either all the time or just during her ult)(also its not like it hasnt been done Diana's like that) because when you have to literally run circles around someone but dont have reliable mobility, it seems to me like it defeats the purpose of her ult entirely. OR, make the cooldown of her riposte significantly shorter. In her current state, at least in my unwanted (at least according to the tards that say silvers cant have opinions) opinion, she's among the least useful champions in the game.
