StormRaider's Surge vs Fiora Riposte bug
I do not know if this should be considered a bug or not, but it was something i found.
Recently I played a match as Nasus vs Fiora. Quite simply the bug is that if she riposte's my Q, and I do the needed damage, Stormraider's Surge will still proc off of it, even though she loses no health. When she would normally be able to outrun me by riposting and dashing away, Stormraider's allowed me to keep up.
That is all, and have a nice day Riot.
