The one and only, Fiora!

So after several games of League a couple days ago before my League bugged out, I have came a crossed the a common issue, and that is, Fiora. This champion has been on my nerves since her first appearances in my League games. She is so incredibly broken, and I suggest a nerf. After every game against a Fiora I usually stop playing League because I have raged so hard, and don't play again for awhile. There are so many things about her that need to be dumbed down, for example: taking away the life steal on her "Blade Waltz" (ult). Not only is she able to be not targeted by anything, but she can go from no health, to full health with the life steal. And while I could go into more details, her being overpowered is so obvious to everyone that I don't think I need to.

Let me know your thoughts about nerfing Fiora, and suggestions would be good. Plz Rito godz, nerf Fiora!
