Ofcourse it does, lets say your ADC got angry that his support didnt use exhaust in a recent 2 v 2 bot lane and died. Got angry and just ran it down mid, and went 0/10 10 mins into the game? What if this is a ranked game where u were hoping to climb and enjoy urself and compete with other players? Honestly no one, I mean no1 regardless of how much of an angel you think you are, will ever be happy about experiencing that.
The non-existant knowledge of your team stems from a massive player base, (27 million people) where probably only 5 million people actually understand the games core, itemization,teamwork, objective control, team compositions and rotations.
No one enjoys losing, but the problem is that too many people that play league of legends(especially the casual players) don't take the time to ask themselves stuff like "what did I do wrong? what could I have done better? Could I of changed my build/positoning?". Most people play league of legends on autopilot, which is fine if you are playing casually. The problem is what they do these kinds of things in ranked. EX 1st timing a champion their just bought in a ranked game.
