Should I buy fiora?

I never wanted to fall into the "I must have a lot of damage and carry champ" mentality but in order to climb I think I need to have more aggressive champs. From there I looked at Fiora. AA reliant melees are considered hypercarries right? Like yi, jax and her and stuff.... Should I buy her? I just want someone who can carry a team if possible. My current tops are: Nasus, malphite and maokai but they really don't have that much kill potential. Maybe malphite with his ult but he's gonna get harassed early on
