Her old W made MUCH more sense to me. Why should a duelist parry spells gives 0 logic.
Playing around auto attacks it was a minigame between me and my opponent.
Remove the passive AD portion of old W and reduce the time where she gets to parry.
COST: 25 MANA COOLDOWN: 10 / 9 / 8 / 7 / 6
ACTIVE: Fiora parries the next enemy basic attack within 0,5 seconds, dealing magic damage to the attacker.
MAGIC DAMAGE: 60 / 110 / 160 / 210 / 260 (+ 100% AP)
And maybe if she parries it succesfully reduce the cd by 1 - 2 secs
Actually I would love to see the old Fiora back completely but that just a dream.
