Change Fiora's True damage

I remember old Fiora. How fun she was, both to play as and against. She was undoubtedly powerful, and she executed squishies in teamfights wonderfully. However when up against heavy armor and thornmail she had met her match. Now a days you could stack all of the health/armor in the world, and she will just destroy you too. How about try kiting her? Nah that's not possible. How about trying to burst her? yea.... about that.....

I think that her mobility and counter mobility could be justified if her damage was quelled. Allowing her to simply puke true damage at a target just seems like terrible game design to me. Let's just back up and get some perspective on what Fiora has become. I would like to change her vitals to something that does Physical damage or reluctantly make it do Magic damage. To help compensate her for this change, I feel like we could make her vitals give her 10% attack speed if it does physical, and 10% movement speed if it does magical. It would last for 3 seconds, and can stack up to 4 times. Every-time a vital is his, the timer resets. This was she can live up to her title as the grand duelist, and she would strive in 1v1s, and not be the grand poo-bah or puke. I would absolutely love to see Fiora dancing around and really dueling a target instead of turning her targets into a pool of bloody true damage.
