Did Arcade Miss Fortunes AA sound change?
I just played a game with the skin and it sounds like her auto attacks changed to be similar to the original or captain fortune.
I might be wrong as I haven't touched her after the nerfs, but they did not sound like the video above. I don't have any video of the issue, but perhaps other people with the skin can test it out. Otherwise I'll try to find a way to record the sound.
