Gameplay: Katarina's Buttons Die.
In matches that last over 30 minutes (it seems to spike more after 45 minutes), 
's buttons seem to give up, namely the Q and R (and B, but you can always RUN back).
When you hit Q, the circle of 'range' shows up and the targeting icon pops up. But if you click anything, you'll move there (often times not even attack).
When you hit R or B, it won't even register, even if you have the use of it (aka: standing on top of a stealthed 
, see the R light up, hit it, nothing happens, you just stand there).
In my last Kat match, I mentioned in the log that the buttons died off. I couldn't Q, at all, and R 'wasn't responding'. So I was literally fighting the enemy with W, E, and items.
- Yes, I know Q has a .5 cast timer. Everything was working fine until around the 30 where there was a 'delay'. Then after 45 minutes in, Q started up with the bug I described.
- I presumed it was the keyboard as I noticed this when I was trying to base and couldn't. But Q brings up the range circle... and everything worked fine until then.
I have heard this from other Kat players when the match goes beyond 30 or 45. Often about their Q not firing.
Sub Note: I was in the 'Slay Belle' skin, the other Kat was in base skin from what I remember. Sub Note 2: I'm on a Windows system.
