I once played a game where the enemy team had a jungle fiora, she was really scary, was always killing everyone. But she was also the only person on her team getting kills so once the game reached a certain point and we got items of our own, we focused her down easily and won the game.

Just because someone in a blue moon does well with a certain comp doesn't make it a good idea. This one fed like hell and didn't manage to get any ganks going, only came and KSed the last hit every time I was about to kill someone.
Going to church doesn't make you a Christian any more than standing in a garage makes you a car.
I once had game full of squishies, and one of them was Jungle Fiora. I went Yorick. I got her a few kills on my lane so she snowballed. Late game we somehow became unstoppable with a 20/x/x Fiora plus her revenant.
She is incredible in the jungle. I got my one and only 2 penta kills with her in the jungle.
The only downside is people catch on fast that you are shredding their team, so they often focus you down, and if you build tanky, you destroy any reason of playing her.
Overall glass cannons have a hard time in this game, to make them work your team essentially needs to be extremely CC heavy. But that isn't really the 'meta' right now so good luck getting that to work solo Q.
