Could we make Fiora an actual Duelist? If not maybe change her title?
From a fencer and old Fiora main I feel like the kit either needs to be altered or Fiora's title needs to be changed from "The Grand Duelist". Part of Fiora's new kit is fun, but its not fluid at all.
Passive:The passive circle takes far to long of a rotation for Fiora to effectively use it. For laning you want to get the most out of your trade and your opponent will know this. Based on the current passive spin time your opponent has to much power over Fiora's passive. It either needs a shorter spin time or the opponent shouldn't be able to see it, Fiora should have some control over her own ability.
Q(Lunge):As a player this ability is still fun, as a fencer it hurts to use. The old Q fit a fencing style much more because of the second lunge/Redouble. It should have a second short dash instead of a CDR reduction for hitting it. It just feels better and fits the theme having a second lunge over its current state.
W(Riposte):I actually like this ability, it feel so much better than shooting a magic bullet. It gives you counter play against being cc chained a few other abilities.
E(Bladework):This ability is actually nice as well, I feel like she gets more out of it that the old E, other than the tower pushing of the old E.
R(Grand Challenge): This is my biggest gripe with the kit. I have no idea how someone came up with giving a 1v1 "Grand Duelist" an AOE heal that is almost impossible to get off in a 1v1. This skill should be about dueling, it should be some other fencing move like a Fleche or call it "En Garde" and have it enhance Fiora's abilities against the target or bonuses against the target.
These are just my thoughts from playing both Fioras and my experience with fencing/sword fighting.
