Gameplay

I just played a ranked match where I lost 16 LP and the match to my team mates which we were totally winning, because after the opposing Alistar knock me up, I as Katarina, got a glitch where I couldn't Q, R, nor B. I re-logged my client, I switched back and forth between normal and smartcast and it wouldn't work. It did the noise as I am pressing a key but It wont let me use it, same as if I point and click with my mouse. So I have lost 16 LP that are so important to me as I was placed in Bronze from Gold V, and I don't think this is fair since it wasn't a mistake on my part but instead on Riot's end.
