@riot about Fiora.
you didn't have to gut fiora. here's what you needed to do:
tl;dr: have a fail state on her ultimate, and have counter play on her passive
in depth, if fiora doesn't win the duel on her ultimate she should have some sort of turnaround where she's hella vulnerable and needs to gtfo. i've seen her ult be used more as a way to say "this person needs to leave the teamfight" rather than "it's you or me [amidst all of them]! let's d-d-d-d-d-d-d-d-d-d-duel!" you can have her do a crap ton of damage like in release so long as she has vulnerabilities in her playstyle.
similarly her passive is just sort of a "hey move over there or I slap you" and feels un-interactive to the enemy laner, who just has to go with the whims of the rng of her passive. how it should work is that if fiora hits one of the vitals, she should gain a vital for a time that can mitigate and or return damage if deft enough, giving the sense of an actual duel.
