Facing Leavebuster for game crash(Who's fault?)

While on game, i was disconnected with a message "Please check your internet connection...." Ok, fine. I checked and found it pretty good. Now that i try to reconnect, it takes several minutes in game loading screen and then again same message...It happened 2 or 3 times may be in this weekend...Well, that's enough to make harassed by leavebuster. Whose fault is it? My internet connection was good still i faced leavebuster because of game crash. #Why should i face Leavebuster? Not only me, many of my friends faced this prob.... I guess its time to leave "League of Legends as well as leavebuster" for me.... #Fkngmtrfkrscantsolvetheirownprob
