Fiora Re-Work Discussion

I have played Fiora for a while and I have always considered her ultimate to be pretty broken but I thought the rest of her kit was okay. I used to have fun using her riposte and lunge in succession, felt like I was playing a fantasy duelist of sorts. Now it feels a little... it's an interesting concept, don't get me wrong, but there's something about it which doesn't scale up right. It feels like I'm playing a whole new champion, one without the same level of time investment I had in the prior. Focusing and honing in on vitals is fun and involves more skill but they seem to spawn too randomly. At times under circumstances where it's too difficult to hit them without taking an enormous amount of damage or risk.

The pay off doesn't seem worth it either a lot of the time. I have very little ideas on what to build since to survive long enough to hit vitals or use her ultimate, it seems to me I should be building tanky - but then I have very little damage... so what type of champion is this exactly? I can't split push effectively anymore either.

She's just too slow. When I pop her ultimate in team fights on my target, hitting all four points without being focused, killed, stunned, etc is near impossible. Her shield is -great- but it takes too long to use. She needs something... not sure what. Like I said. I'm enjoying it to an extent but I find her ultimate underwhelming and the 'vitals' system far too luck based on where they spawn/etc.
