[CRASH] Unexplainable crashes in League of Legends.

Here's what happenned:

I press B. Game crashes, but not in the usual way. "Attempting to Reconnect" flickers in the top of the screen. I check my connection and find out that my computer is connected to the Internet. This is what ypu can see in the video.

Whay you don't see is that I got sent to LeaverBuster after this. This is incredibly ridiculous, as it isn't the first time this has happenned. It has happenned sonewhere between 20 or 30 times and it has gotten me placed in LeaverBuster over 10 times.

This is ridiculous. This is a CO OP vs AI game. Another player was experiencing the same issue. There's nothing else I can do on my end. My internet is expensive, all the devices are disconnected when I play League of Legends, and I make sure the client is the number one priority program.

I can't believe that it's been nearly 5 patches or more since this problem has started and no one can explain what's going on. When I first started playing (somewhere around 5.4), the game was very stable. I could play League of Legends in high quality using my university's WIFI without a problem, and now I can't play a single game where my ping is 300 or more and my fps is less than 10. These crashes are killing me and are wasting my time, and this LeaverBuster garbage doesn't make it better.

Seriously, all I am playing is CO OP vs AI because I don't want to ruin anyone's game by disconnecting randomly because Riot won't take a look into this. If nothing will be done about this or about LeaverBuster, then please give me my money back so I can spend it on a game that works.

Note: I had just finished my previous LeaverBuster queues when this happenned. As you can see, whoever created it downright lied when they said it would take multiple offenses to get into LeaverBuster.

Also the reason why I didn't send a ticket was because I actually did. A ton of times. And not no help in return.
