A lot of players overestimate their understanding of the game. They decide a game is lost at some point and help ensure it stays lost by talking or generally behaving like a bag of potatoes. I blame the streamers. They decide a game is lost, tell their viewers the game is lost and proceed to play in a way that will help fulfill their prophecy. "Shucks, I will have lost a game on smurf number 9 which I kind of don't care about at all but at least I was able to call it at minute 7 which shows my deep understanding of the game" Then their viewers proceed to do the same. Monkey see monkey, monkey angry.
