"Yorick" the screen lock mode already
I've personally only have very unpleasant experiences with it. Sometimes it's a mid-game and I accidentally press Y, then spent the next 5 minutes afk trying to get rid of it. Or more recently, the lockscreen bug which cannot be turned off by normal means (hotkey/on screen key) This mode needs to be buried somewhere noone can find (preferredly with teemo :) ). It brings more trouble than usefulness.
