I love the Headmistress Fiora skin. But the sound effects are just wrong. She was supposed to have new sound. I haven't played classic Fiora, but Headmistress Fiora sounds as if she is using a sword to slash things, not a ruler to smack things.
This is most apparent during Blade Waltz, where the sound is crisp and separated by silence. Each attack is a distinct slash, instead of a smack.
I understand that she is using the correct sound effects, but I suggest that those sound files should be given a second look and modified slightly.
Tryndamere's autoattack is a good example of what smacking sounds like. Headmistress Fiora's sound effects are nothing like that.
