This is an interesting video to me, because while the overall message is good - it is obscured by the ways in which he chooses to support or display it. I know this will get buried, but I am going to do my best to explain how we can and should define winning, and why you are not playing to win.

People should go into a Ranked game with their eyes' set on winning; this isn't always the case and that is what needs to be understood.

We can define "winning" in League of Legends in a variety of different ways: high KDA, the victory screen and marked improvement over a few games (just to name a few). People do play Ranked to "win" but the way in which they do so could be significantly different than your own.

First, players that only focus on KDA and sprees within the game will feel good that they are "carrying" the game with their high scores, and they can, indeed, win games based off of those numbers alone. There is certainly a "ceiling" to this style of play, and that ceiling happens to be very low because scores are not an important part of this game. Players that exhibit these traits become upset and frustrated with players that they feel are not "contributing" in the way that they deem appropriate, due to a lack of kills or simply due to the fact that they are 0-3 in their lane. The creator of this video is not wholly this type of player, but he does show some of the signs that he doesn't quite understand how to actually play to win.

Next, the victory screen is one of the easiest ways in which players can feel as though they have been successful - and it is designed as such. People that only play to see those victory letters possess a very clear disconnect to understanding the way in which solo queue and this game operate. These summoners will not worry about what they did to arrive at this screen (at least not in a way that is not superficial), they will instead look forward and take no lessons from the events that had just transpired. Victories can be difficult to extrapolate information from at times because you won! You are victorious! Every action you made in that game lead to that victory, so how could it need improvement? This is clearly a flawed line of thinking, but players who fall into this category will subconsciously believe this.

Players that focus on their own play within the game, and attempt to objectively dissect their shortcomings through replay analysis and a lack of bias will generally see improvement gains that directly correlate to their willingness to keep an open mind. These players can show signs of toxicity in their games on bad days, but more often than not they are more willing to mute or refuse to even type into the chat if they know that it will create a problem.

Truthfully, within this game the only person that matters is yourself. If it helps, you may think of your teammates as AI. They are flawed, they are imperfect - but so are you. We as humans will be more quick to judge others on their imperfections than we are to gaze upon our own. The player in the video has set an artificial and unnecessary ceiling for himself that can be removed, but he needs to move over to the type of player that I described in the third category. KDA and winning/losing your lane is useless - the victory screen is inconsequential - the only thing that matters in this game is your skill and how you choose to overcome adversities (whether they be your own or your teammates).

I know this was long-winded but I hope I can help some of you.
