It's all good guys, riot balance team will nerf fiora
Nevermind her ability to instant stack fervor, have pretty damn good damage in lane for a hyperscale, and decent sustain thanks to buffs received in this patch http://na.leagueoflegends.com/en/news/game-updates/patch/patch-614-notes
"Looking at her still. Current avenue of testing is reduction in movement speed from Passive/Ult, to see whether that's giving her excessive control in match ups where she shouldn't be as effective in particular (e.g. against other mobile champs)." - Meddler
LOL how about you hit her actual early game damage, and maybe even take back that 5 healing buff with the vitals.
patch 6.14 was a different time, fervor didn't do all too much for fiora since it was on hit damage, but times have changed, and fervor in particular has shown to be a huge power increase for fiora due to her asinine AD scalings. I personally believe fervor isn't really the issue, but fiora's interaction with it is, so to compensate for fervor being so damn good on her, she needs to be hit directly where it hurts.
