Fiora and Season 5

In the past, everyone joked about Fiora being a useless champion and how unreliable she is. But as of late, tanks became steadily phased out and people often delay their Zhonyas (if they're an AP mid or a very mean Teemo) until they get over their 'muh mana regan tho' woes or are simply resourceless, meaning she could potentially ult without punishment.

And with the way the jungle works, camping her would lead to less-than-best results, as they lose dragon pressure for nearly half the game, will definitely be behind in levels and even when camped, all she needs is her Hydra before she will threaten many without being double-teamed if not severely behind.

In fact, she thrives on top lane being a lonely island as she mercilessly scales up quickly to a turret destroying, tower diving, counterjungling wave of destruction. Sure you can throw all the cc you want at her, but if she doesn't die, she can still press R over your team and then you'll be out of cc to win a fight, essentially becoming an aggro tank while being a glass cannon (solo queue dream).

And since I play a pretty decent Fiora (As in I cheat with taking Exhaust if I think their top may be a problem early on or their name is Riven or Pantheon), I am curious as to what people think before we hit season 5.

Is she underestimated in our current environment or am I just lucky?
