Now that Kat's WR has dropped 2%, can we fix her W?
I have no idea how to reproduce it but what I do know is that is has been bugged since her update. When pushing buttons rather quickly as all Kat mains do, her W on occasion simply DOES NOT WORK after using E. I'm pretty sure it doesn't work even if you press it a couple times within a short window, but eventually does work after it's too late (time is very important in Kat combos for obvious reasons). The easiest way to tell that the bug occurred is if you use E later while W is up, and Kat just automatically uses W without giving the input.
