So Fiora has amongst the lowest win rate top laners right now, and I'm seeing every Fiora take Press the Attack... which just seems like a bad idea to me... because this path forces you to have Attack Speed, and Fiora is extremely reliant on AD rather than Attack Speed.
Meanwhile, the Sorcery/Domination paths don't seem to offer keystones that really fit her playstyle, that's why...
Inspiration + Domination/Sorcery as secondary!
I tried Kleptomancy and Glacial Augment (both of which proc on your Q!) and they work really well.
Just wanted to share ^_^
