Fiora's re-work, i found the solution
The solution to Fiora's re-work is not her ult like we thought, it is her W. Fiora's W is out of place with her kit, to activate she must be stationary and take a .75 immobility, this results in a semantic and practical limitation, semantically, Fiora is a duelist/fencer. Fencers dont only stay stationary to parry, they can parry while lunging and evading. However, Fiora does not have the capability to parry while lunging.
Practically, every time Fiora parries she must be immobile/stationary and this contradicts her Ult, had she been more mobile, she would have a better chance to hit her enemies vitals. using W is setting you back if you have an ult ready.
Possible Solution: make Fioras parry mobile, when activated not only does she parry/cc, but she lunges forward or backward depending on mouse movement, (Riot's team can decide how to implement that).
Scenario 1:
vs
, jax set's up his stun, fiora lunge parries (W) to jax, stuns him, then hit's his vital spot, then she activates her ulti (R), then (E) strikes 1 vital spot, lunges (Q) towards the other spot, then with 2 vital spots left it is up to the skill of the player to finish.
Scenario 2:
vs
in this scrimmate things arent looking well for Kat, so she decides to run, but lux is tricky, her stun can connect rendering kat really vulnerable and possibly taking the kill, all of a sudden Fioras (W) lunge parries lux's stun and saves Kat. Then Kat and your team congradulates you with a 'gj'.
But wait! so Fiora's (Q) and (W) are lunges? isnt that too many lunging? if you decided to double lunge for mobility the mana must cost you to keep this balanced, i think with good cooldown reduction people might abuse 2 dashes so Riot can increase the mana cost by alitle.
Problem 2: cool downs on her skills, yes the cd's are huge, Riot should reduce q/w/e cd by atleast 15%
Problem 3: After Fiora uses her ult, we need cool down reduction like Kat, this way Fiora is good in team fights.
