GAME BREAKING BUGS, RIOT NEEDS TO SEE THIS

The game keeps randomly freezing. It's happened to me twice, and it's happening to so many other people as well. Now, for some reason this has only happened to me while playing as Kayn, but I think that's just coincidental. Either way, until this bug gets fixed I refuse to play LoL. I don't want to risk losing another game just because my screen randomly froze on me, nor do I want to risk getting punished for something that's out of my control. Also, a lot of people have been having problems loading into the game. Personally, I haven't experienced this issue, but regardless it's nothing to shake a finger at.
