FurretHasAGlock1 votesFor vayne- build things like 
and 
. These items are good against her to slow her attack speed, thus lowering procs of silver bolts. Also, try using champs like 
and 
who have attack speed slows, which can counter vayne, and both have lots of CC/mobility reducing spells to prevent getting away from vayne.
For Fiora- Reducing her damage through means of armor, while they may not be perfect, works. Additionally, use champs with multiple dashes (Ex; 
) To be able to counter her when she tries to get to the vitals.
A few items that might work would be 
(Not positive if it removes, needs testing.) I think 
removes the debuff of the vitals, 
cuts the time she has for her ult in half.
Champions- using champs such as 
can counter fiora, with his legendary mobility, as well as 
can keep up with fiora mobility, allowing them to either escape, outspeed, and more. The best part is that both of these are pretty good duelists as well.
venomous frost1 voteswith vayne you can either kill her with an assassin, or play AS slowing champs like malphite.
in fiora's current state: ban her.
Iqqi1 votesFiora passive is very broken. It is like the same as the original Kha'Zix passive before they changed it. Somehow that deserved to be altered, but the Fiora passive remains. These kinds of LoS passives damage increases are so terrible by design. Enjoy walking out of lane or in a bush every 5 seconds to clear the buff. That is not good game play design. Fiora rework was a complete failure in every way.

It really wasn't, just because you can't face roll as any tank and win doesn't mean it was a failure.
